+# VM Testbase landing
+
+This directory serves as a _temporary_ landing place for tests converted from so-called VM testbase.
+Most of these tests have been written a long time ago, don't meet modern coding
+standards, guidelines and are in need of reworking.
+Eventually, all the tests located here should be reworked and moved accordingly to
+regular JTReg test suite directory layout convention, i.e. following the same
+layout as product code as close as possible.
+
+New tests must **not** be added into this directory.

+/**
+ * Parser for JDI test's command-line arguments.
+ * <p>
+ * Test's command line may contain two kind of arguments, namely:
+ * <ul>
+ * <li> options for ArgumentParser
+ * <li> other arguments for the test itself
+ * </ul>
+ * <p>
+ * We call <i>raw arguments</i> the <code>args[]</code> array
+ * passed to the test's method <code>main(String args[])</code>.
+ * ArgumentParser instance initialized with raw arguments serves to parse
+ * these two kinds of arguments. Use <code>ArgumentParser(args[])</code>
+ * constructor, or <code>setRawArguments(args[])</code> method
+ * to initialize a ArgumentParser instance with particular raw arguments.
+ * <p>
+ * Arguments, started with ``<code>-</code>'' symbol are called <i>options</i>.
+ * They are recognized by ArgumentParser and are used by support classes
+ * (such as Log, Binder, etc.).
+ * These options should be specified in the following general form:
+ * <ul>
+ * <li> <code>-option=<i>value</i></code>
+ * </ul>
+ * or
+ * <ul>
+ * <li> <code>-option <i>value</i></code>
+ * </ul>
+ * List of the recognized options with their values may be obtained by
+ * invoking method <code>getOptions()</code> that returnes
+ * a <code>Properties</code> object with options values.
+ * It is not recommended to get options value directly. An appropriate methods
+ * such as <code>verbose()</code>, <code>getArch()</code>, etc. should be used
+ * instead.
+ * Options may appear in the test command line in any order.
+ * <p>
+ * All the other arguments of command line are called <i>test arguments</i>
+ * (or simply <i>arguments</i>). These arguments should be handled by test itself.
+ * Full list of the test arguments in the same order as they appears in the command line
+ * may be obtained by invoking method <code>getArguments()</code>.
+ * <p>
+ * Following is the list of basic options accepted by AgrumentParser:
+ * <ul>
+ * <li> <code>-arch=</code><<i>${ARCH}</i>> -
+ * architecture name
+ * <li> <code>-waittime=</code><<i>minutes</i>> -
+ * timeout in minutes for waiting events or so
+ * <li> <code>-verbose</code> -
+ * verbose Log mode (default is quiet)
+ * <li> <code>-trace.time</code> -
+ * prefix log messages with timestamps (default is no)
+ * </ul>
+ * Also AgrumentParser supports following stress options (see nsk.share.test.StressOptions for details):
+ * <ul>
+ * <li> <code>-stressTime</code>
+ * <li> <code>-stressIterationsFactor</code>
+ * <li> <code>-stressThreadsFactor</code>
+ * <li> <code>-stressDebug</code>
+ * </ul>
+ * <p>
+ * Note, that the tests from the particular subsuites have its own argument handlers
+ * wich accepts additional options. See <code>jpda.DebugeeArgumentHandler</code>,
+ * <code>jdi.ArgumentHandler</code>, <code>jdwp.ArgumentHandler</code>.

+ * Class used as an agent for Java serviceability reliability testing (RAS).
+ * It sets different RAS options and/or modes for a special agent which

+ * The agent recognizes arguments, started with ''<code>-ras.</code>''. They
+ * may be as follows:<p>
+ * <li><code>-ras.help</code> - print usage message and exit
+ * <li><code>-ras.verbose</code> - verbose mode
+ * <li><code>-ras.invoke_run</code> - invoke the method <i>run(String[],PrintStream)</i>
+ * of the test instead of <i>main(String[])</i> which is invoked by default.
+ * <li><code>-ras.hotswap=<stress_level></code> - enable JVMTI hotswap of
+ * the currently running test classes. Here are the possible HotSwap stress
+ * levels:<br>
+ * 0 - HotSwap off<br>
+ * 2 - HotSwap tested class in every JVMTI method entry event of running test
+ * (default mode)<br>
+ * 20 - HotSwap tested class in every JVMTI method entry event of every class<br>
+ * 3 - HotSwap tested class in every JVMTI single step event of running test<br>

+---------------------------------------------------------------------------------
+
+Naming conventions
+
+Classes:
+
+ All shared classes are groupped into packages to prevent
+ name collision.
+
+ All classes exported directly from this directory are
+ of package:
+
+ nsk.share
+
+ All classes exported from subdirectories are of particular
+ subpackage, e.g.:
+
+ nsk.share.jpda
+ nsk.share.jdwp
+ nsk.share.jdi
+ nsk.share.jdb
+ nsk.share.monitoring
+ nsk.share.sysdict
+
+Native functions and macroses:
+
+ Most native functions have special prefix to prevent linking collisions.
+ Most macroses also have special prefix and are wrote in upper register.
+
+ Here is typical naming scheme used for native functions and macroses:
+
+ share/native
+ functions: nsk_*
+ macroses: NSK_*
+
+ share/jni
+ functions: nsk_jni_*
+ macroses: NSK_JNI_*
+
+ share/jvmti
+ functions: nsk_jvmti_*
+ macroses: NSK_JVMTI_*
+
+ However, some native functions and macroses do not follow this scheme,
+ in order to preserve compatibility with old tests.

+
+AbstractJarAgent is base class for java agents used in AttachOnDemand tests
+(tests against Attach API, API from package com.sun.tools.attach).
+
+In all AttachOnDemand tests the same algorithm is used:
+ - java application where agent is loaded to (target application) based on
+ class nsk.share.aod.TargetApplicationWaitingAgents starts and waits when
+ test agents will be loaded
+
+ - special application (nsk.share.jvmti.aod.AgentsAttacher) loads test agents
+ in the target application using Attach API
+
+ - when agent is loaded it notifies target application about that and executes
+ test-specific actions. When agent execution is completed it also notifies
+ target application about that
+
+ - when all test agents finish execution target application checks its status
+ (passed or failed) and also finishes
+
+Each java agent should have method 'agentmain' where only agent initialization should be done,
+main agent's actions should be executed in special thread started from 'agentmain'.
+Class AbstractJarAgent incapsulates actions common for all java agents: agent initialization,
+starting thread executing agent's actions and communication with target application.
+
+In most cases test agents should override only method 'agentActions' and its 'agentmain'
+should contain only call of the method 'AbstractJarAgent.runJarAgent'.
+
+Typical agent class looks like this:
+
+public class agentExample extends AbstractJarAgent {
+
+ protected void init(String[] args) {
+ // parse agent's options and do test-specific initialization
+ }
+
+ protected void agentActions() {

+Class TargetApplicationWaitingAgents is part of the framework used in the AttachOnDemand tests
+(tests against Attach API, API from package com.sun.tools.attach).
+
+Attach API allows to load so called 'agents' in the running VM. In terms of this framework
+application running in the VM where agent is loaded to is called 'target application'.
+
+TargetApplicationWaitingAgents is base class for target applications used in the AttachOnDemand tests
+(also TargetApplicationWaitingAgents can be used without modifications in tests where target
+application shouldn't execute some test-specific actions).
+
+AttachOnDemand tests requires synchronization between test agents and target application:
+ - before target application can start to execute test-specific actions it
+ should wait when all tests agents will be loaded
+
+ - target application shouldn't finish until all agents finish their work
+
+TargetApplicationWaitingAgents incapsulates actions common for all target applications. TargetApplicationWaitingAgents
+provides 2 methods: 'agentLoaded' and 'agentFinished', test agents use these methods to notify
+target application about its status. When target application based on the TargetApplicationWaitingAgents
+starts it first waits when all test agents will be loaded (number of expected test agents is
+passed via parameter -agentsNumber). After this target application executes test-specific actions,
+waits when all test agents will finish, checks agent's status (passed of failed) and
+finishes.
+
+In most cases test target applications should override only method 'targetApplicationActions' and
+its 'main' method should contain only call of the method 'TargetApplicationWaitingAgents.runTargetApplication'.
+
+Typical target application class looks like this:
+
+public class targetExample extends TargetApplicationWaitingAgents {
+
+ protected void targetApplicationActions() {
+ // do test-specific actions
+ }
+
+ public static void main(String[] args) {

+ *
+ * - for each test from input file:
+ *
+ * - SerialExecutionDebugger creates object of current debugger and initializes it with already created pipe and debuggee
+ * - SerialExecutionDebugger sends command to SerialExecutionDebuggee: 'COMMAND_EXECUTE_DEBUGGEE <CurrentDebuggeeName>'
+ * (CurrentDebuggeeName name should provide current debugger), and waits READY signal from debuggee
+ * - SerialExecutionDebuggee parses received command, extracts debugee name, creates object of current debuggee, which should be
+ * subclass of nsk.share.jpda.AbstractDebuggeeTestName
+ * - SerialExecutionDebuggee executes current debuggee's method 'doTest()', in this method debuggee sends signal READY
+ * and waits debugger command
+ * - SerialExecutionDebugger receives signal READY and executes current debugger's method 'doTest()', in
+ * this method debugger should perform test
+ * - when debugger method doTest() finishes SerialExecutionDebugger checks is this test passed or failed and

+---------------------------------------------------------------------------------
+
+This directory contains source files of testbase_nsk JNI framework,
+which provides support for JNI tests and accessing JNI environment.
+
+ Source files:
+ jni_tools.h
+ jni_tools.c
+
+ Naming conventions:
+ macroses: NSK_JNI_*
+ functions: nsk_JNI_*
+
+---------------------------------------------------------------------------------
+
+jni_tools.h
+
+Provides functions and macroses for invocation of JNI functions
+and checking JNI errors and pending exceptions:
+
+ NSK_JNI_VERIFY(jni, action)
+ NSK_JNI_VERIFY_NEGATIVE(jni, action)
+
+Typical example of usage of NSK_JNI_VERIFY and NSK_CPP_STUB macroses
+for invokation of JNI functions:
+
+ // jni->FindClass(jni, class_name)
+ if (!NSK_JNI_VERIFY(jni,
+ NSK_CPP_STUB2(FindClass, jni, class_name) != NULL)) {
+ return JNI_ERR;
+ }
+
+or with saving obtained data:
+
+ // cls = jni->FindClass(jni, class_name)
+ if (!NSK_JNI_VERIFY(jni, (cls =
+ NSK_CPP_STUB2(FindClass, jni, class_name)) != NULL)) {
+ return JNI_ERR;
+ }

+ * <p>
+ * This utility should be started on remote host. It listens for connection

+ * <p>
+ * <code>BindServer</code> works together with <code>Binder</code> used in
+ * the tests to incapsulate actions required for launching debuggee VM.
+ * See <code>ProcessBinder</code> and <code>DebugeeArgumentHandler</code>
+ * to know how run tests in local or remote mode across network or
+ * on an single host.
+ * <p>
+ * <code>BindServer</code> is started on the debuggee host.
+ * It recognizes following command line options:
+ * <ul>
+ * <li><code>-bind.file=<i>filename</i></code> - configuration file
+ * <li><code>-verbose</code> - print verbose messages
+ * </ul>
+ * <p>
+ * Only required option is <code>-bind.file</code>, which points to the file
+ * where pairs of particular pathes are presented as they are seen from
+ * both hosts along with some other <code>BindServer</code> options.
+ * See <i>execution.html</i> to read more about format of bind-file.

+ * byte to short, int, long, float, or double
+ * short to int, long, float, or double
+ * char to int, long, float, or double
+ * int to long, float, or double
+ * long to float or double

+ * char to byte or short
+ * int to byte, short, or char
+ * long to byte, short, char, or int
+ * float to byte, short, char, int, or long
+ * double to byte, short, char, int, long, or float

+Examples:
+ Conversions (int)1234567890 -> (float)1.23456794E9 and (float)1.5 -> (int)1 loose precision.

+/**
+ * This class provides debugger with ability to launch
+ * debuggee VM and to make connection to it using JDI connector or
+ * JDWP transport.
+ * <p>
+ * The present version of <code>Binder</code> allows
+ * to launch debuggee VM either on local machine (<i>local</i> launch mode),
+ * or on remote host using <code>BindServer</code> utility
+ * (<i>remote</i> launch mode). Also there is an ability to launch
+ * debuggee VM manually as a separate process on local or remote machine
+ * (<i>manual</i> launch mode), which is usefull for debugging.
+ * All these launching modes are specified by command line option
+ * <code>-debugee.launch</code> recognized by <code>DebugeeArgumentHandler</code>.
+ * <p>
+ * <code>Binder</code> also makes it possible to establish TCP/IP
+ * connection between debugger and debuggee throw <code>IOPipe</code>
+ * object. This connection allows debugger to communicate with debuggee
+ * by exchanging with synchronization messages and data.
+ * <p>
+ * To launch debuggee VM and bind to it use <code>bindToDebugee()</code>
+ * method. This method construct mirror of debugee VM, represented by
+ * object of <code>DebugeeProcess</code> class or derived. This mirror object
+ * allows to control debuggee VM.
+ * <p>
+ * See also <code>nsk.share.jdi.Binder</code> and <code>nsk.share.jdwp.Binder</code>

+ * JDI and JDWP features.

+ * (this object creates server socket and waits for incoming connection) and client
+ * SocketIOPipe (this object attaches to server).
+ *
+ * Server and client objects should be created using special static methods provided by this class,
+ * for example 'createServerIOPipe(Log log, int port, long timeout)' for server SocketIOPipe
+ * and 'createClientIOPipe(Log log, String host, int port, long timeout)' for client SocketIOPipe.
+ *
+ * When SocketIOPipe is created it can be used to send and receive strings using methods 'readln()' and 'println(String s)'.
+ * TCP/IP connection is established at the first attempt to read or write data.
+ *
+ * For example, if client process should send string 'OK' to the server process which is run
+ * at the host 'SERVER_HOST' following code can be written:
+ *
+ * Server side:
+ *
+ * // SocketIOPipe creates ServerSocket listening given port
+ * SocketIOPipe pipe = SocketIOPipe.createServerIOPipe(log, port, timeoutValue);
+ *
+ * // SocketIOPipe waits connection from client and reads data sent by the client

+ *
+ * // initialize SocketIOPipe with given values of server host name and port
+ * SocketIOPipe pipe = SocketIOPipe.createClientIOPipe(log, 'SERVER_HOST', port, timeoutValue);

+---------------------------------------------------------------------------------
+
+This directory contains source files of testbase_nsk native
+framework, which provides support for native tests.
+
+ Source files:
+ nsk_tools.h
+ nsk_tools.c
+
+ Naming conventions:
+ macroses: NSK_*
+ functions: nsk_*
+
+Also this directory provides support for running native threads
+in a platform independent manner.
+
+ Source files:
+ native_thread.h
+ native_thread.c
+
+ Naming conventions:
+ functions: THREAD_*
+
+The following source files declares a set of functions which
+provides support for lists of various objects
+
+ Source files:
+ nsk_list.h
+ nsk_list.c
+
+ Naming conventions:
+ functions: nsk_list_*
+
+---------------------------------------------------------------------------------
+
+nsk_tools.h
+
+Provides functions and macroses for the most usefull actions:
+
+ - access native JVM environment in a compiler independent manner
+
+ NSK_CPP_STUBn(function, env, arg1, ..., argn)
+
+ - print error message with arguments
+
+ NSK_COMPLAINn(format, arg1, ..., argn)
+
+ - print verbose message with arguments
+
+ NSK_DISPLAYn(format, arg1, ..., argn)
+
+ - trace action execution
+
+ NSK_TRACE(action)
+
+ - trace action, check result for true/false and print error if required
+
+ NSK_VERIFY(action)
+ NSK_VERIFY_NEGATIVE(action)
+
+ - set verbose and trace mode of test output
+
+ void nsk_setVerboseMode(int verbose);
+ int nsk_getVerboseMode();
+
+ void nsk_setTraceMode(int mode);
+ int nsk_getTraceMode();
+
+ - miscelaneous functions for printing messages
+ (hidden by above mentioned macroses)
+
+Typical example of using macroses NSK_CPP_STUB and NSK_VERIFY
+for accesing JVM native environment:
+
+ // jvm->GetEnv(jvm, &env, version)
+ if (!NSK_VERIFY(
+ NSK_CPP_STUB3(GetEnv, jvm, &env, JNI_VERSION_1_2) == JNI_OK)) {
+ return JNI_ERR;
+ }
+
+For more specific checks in invocations of JNI and JVMTI functions
+use special macroses defined in share/jni and share/jvmti frameworks.
+
+---------------------------------------------------------------------------------
+
+native_thread.h
+
+Provides platform-independent support for running native threads:
+
+ - manage native threads
+
+ void* THREAD_new(PROCEDURE procedure, void* context);
+ void* THREAD_start(void* thread);
+ void THREAD_waitFor(void* thread);
+ void THREAD_sleep(int seconds);
+
+ - get status of native threads
+
+ int THREAD_isStarted(void* thread);
+ int THREAD_hasFinished(void* thread);
+ int THREAD_status(void* thread);
+
+---------------------------------------------------------------------------------
+
+nsk_list.h
+
+Provides support for lists of various objects:
+
+ - managing list
+ const void* nsk_list_Create();
+ int nsk_list_Destroy(const void *plist);
+
+ - managing elements
+ const void* nsk_list_Add(const void *plist, const void *p);
+ int nsk_list_Delete(const void *plist, int ind);
+
+ - getting element info
+ int nsk_list_getCount(const void *plist);
+ const void* nsk_list_Get(const void *plist, int ind);
+
+Typical example:
+
+int TOTAL_COUNT = 10;
+typedef struct recordStruct {
+ int field1;
+ int field2;
+} record;
+
+main() {
+ int i;
+ record *rec;
+ const void *plist;
+
+ /* creating list */
+ plist = nsk_list_create();
+
+ /* adding new elements */
+ for (i = 0; i < TOTAL_COUNT; i ++) {
+ rec = (record *)malloc(sizeof(record));
+ rec->field1 = i;
+ rec->field2 = i * 10;
+ if (!nsk_list_add(plist, rec)) {
+ free((void *)rec);
+ }
+ }
+
+ /* getting elements */
+ for (i = 0; i < TOTAL_COUNT; i ++) {
+ rec = (record *)nsk_list_get(plist, i);
+ printf("%3d %3d\n", rec->field1, rec->field2);
+ }
+
+ /* deleteing elements */
+ for (i = 0; i < TOTAL_COUNT; i ++) {
+ rec = (record *)nsk_list_get(plist, i);
+ free(rec);
+ nsk_list_remove(plist, 0);
+ }
+
+ /* destroying list */
+ nsk_list_destroy(plist);

+/**
+ * This framework allows one to automate parsing of the test command line
+ * arguments (it automatically sets the corresponding fields of the
+ * test class).
+ <p>
+<h3>A simplified example</h3>
+Suppose we want to to define a test Test with an option "iterations",
+which can be run via
+</p>
+<pre> > java Test -iterations 10 </pre>
+or via
+<pre> java Test </pre>
+in the last case iterations defaults to 100.
+<p>
+We want to achieve this by annotating fields of the Test class by
+a special @Option annotation.
+<p>
+For simplicity suppose @Option is defined as follows:
+<pre>
+ @interface Option
+ { //here all the annotation fields are mandatory
+ String name();
+ String default();
+ String description();
+ }
+ </pre>
+ The test class uses an API like:
+ <pre>
+ public class OptionSupport {
+ public static void setup(Object test, String[] args);
+ }
+</pre>
+Now a simple example:
+<pre>
+public class Test {
+
+ @Option( name="iterations",
+ default="100",
+ description="Number of iterations")
+ int iterations;
+ public void run() {
+ // ..do actual testing here..
+ }
+
+ public static void main(String args) {
+ Test test = new Test();
+ OptionsSupport.setup(test, args); // instead of manually
+ // parsing arguments
+ // now test.iterations is set to 10 or 100.
+ test.run();
+ }
+}
+</pre>
+This test can be also run via
+<pre>
+- java Test -help
+</pre>
+Then OptionSupport.setup() shows
+help and exits (by throwing exception?):
+<pre>
+ Supported options:
+ -iterations <number>
+ Number of iterations (mandatory)
+</pre>
+We also want to be able to apply this to fields of non-simple types (via
+factories) and to other classes recursively (see @Options annotation
+below).
+<p>
+Please, see {@link vm.share.options.test.SimpleExample}
+for a working version of this.
+ * <h3> General description </h3>
+ Options are defined using annotations like this:
+<pre>
+public class StressOptions {
+ // [2]
+ @Option(name="stressTime",
+ default_value="60",
+ description="Stress time")
+ private long stressTime;
+
+ ...
+}
+</pre>
+<p> we want to use command line like
+<pre> java Test -stressTime 50 </pre>
+here 50 is passed to the StressOptions.stressTime field.
+see {@link vm.share.options.Options} below. </p>
+<pre>
+public class Test {
+ // [1]
+ @Options
+ StressOptions stressOptions = new StressOptions();
+
+ // [2]
+ @Option(name="iterations",
+ default_value="100",
+ description="Number of iterations")
+ int iterations;
+
+ // [3]
+ @Option(
+ name="garbageProducer",
+ default="byteArr",
+ description="Garbage producer",
+ factory="nsk.share.gc.gp.GarbageProducerFactory")
+ GarbageProducer garbageProducer;
+...
+
+ // [4]
+ @Option(name="logger",
+ description="Logger",
+ factory="nsk.share.log.LogFactory")
+ Log log;
+
+ public void run() {
+ log.info("Start test");
+ log.info("Finish test");
+ }
+
+ public static void main(String[] args) {
+ Test test = new Test();
+ OptionsSupport.setup(test, args);
+ test.run();
+ }
+}
+</pre>
+<p> The API is invoked via a call to {@link vm.share.options.OptionSupport#setup(Object, String[])}).
+ Also there is {@link vm.share.options.OptionSupport#setup(Object, String[], OptionHandler)}) method.
+ It allows the caller to pass a handler which takes
+ care of the options not defined via @Option annotation.
+</p>
+
+<h3>Requirements</h3>
+<p>
+ - The following field types are supported out-of-box: [2]
+ <ul>
+ <li/>All basic (primitive) types (int, long, ...) and corresponding wrapper types.
+ <li/> In the case of a boolean type option user is allowed to skip second argument,
+ i.e. write '-option_name'
+ instead of '-option_name true'.
+ <li/> Strings.
+ <li/> One dimentional arrays of the above (comma-separated).
+ <li/> Classes if a factory is specified, see below.
+ <emph>NOTE: currently there is no way to pass some options to the instantiated objects.</emph>
+ </ul>
+</p>
+<p> All non-static fields (including private and protected) of class and
+ it's superclasses are scanned for annotations.
+</p>
+<p>
+ (Possibly) Same annotations for setter methods ? (NOT IMPLEMENTED)
+</p>
+<p>
+ It is possible to inherit options of the field type
+ through @Options annotations, see {@link vm.share.options.Options}, and [1] above.
+</p>
+<p>
+ Option.name defaults to the name of the field.
+</p>
+<p> Object options are supported using {@link vm.share.options.OptionObjectFactory}, see [3] above.
+Please see {@link vm.share.options.OptionObjectFactory} interface, it should be
+implemented by the user and specified in the Option.factory attribute.
+</p>
+<p>
+As a shortcut we provide BasicOptionObjectFactory class, which allows user to
+create a factory via @{@link vm.share.options.Factory} annotation:
+<pre>
+@Factory (
+ placeholder_text="garbage producer", //used for generating <..> in the help message
+ default_value="byteArr",
+ classlist={
+ @FClass(key="byteArr",
+ type="nsk.share.gc.gp.array.ByteArrayProducer",
+ description="byte array producer")
+ @FClass(key="charArr",
+ type="nsk.share.gc.gp.array.CharArrayProducer",
+ description="char array producer")
+ ...
+ }
+)
+public class GarbageProducerFactory extends BasicOptionObjectFactory {
+}
+</pre>
+<p> <emph> note: for subclasses of BasicOptionObjectFactory
+factories can extend each other!!
+so the check for @OptionObjectFactory is done recursively.
+NOT SURE IF THIS IS IMPLEMENTED.
+</emph></p>
+<p> If there is no unknownOptionHandler then in case of unsupported
+option, a Runtime exception is thrown.
+</p>
+<p>
+ If there is no 'default' annotation attribute and there is no default
+for OptionObjectFactory, then option is mandatory and a Runtime exception is thrown if
+it's missing.
+</p>
+ <p> Both '-option value' and '-option=value' formats are supported.
+ </p>
+<p> If main class is given '-help', OptionSupport.setup() shows
+help and exits (by throwing a Runtime exception):
+<pre>
+Supported options:
+ -iterations <number>
+ Number of iterations (mandatory)
+ -stressTime <number>
+ Stress time (default 60)
+ -garbageProducer <garbage producer>
+ Garbage producer (default byteArr). Supported keys:
+ byteArr byte array producer
+ charArr char array producer
+ ...
+ ...
+</pre>
+
+<p> <emph> NOT IMPLEMENTED: </emph>
+Integer type boundaries are validated with RuntimeException with detailed
+meaningful error message. Other validations that are possible are also done.
+</p>
+ <p> <emph> NOT IMPLEMENTED: </emph>
+ Empty default ("") value for Object annotations [3] means null value.
+</p>
+<p> The object created via factory is also scanned for @Option annotations
+(like in the @Options case), i.e. it inherits options from the Test class.
+<emph> This is not implemented as it causes several problems, in particular, the
+object must be instanciated in order to be scanned for options, hence no meaningful
+help message could be generated for corresponding options.
+One of the possible solutions
+is to allow -object_opt_name.suboption syntax (or even with a colon), and to pass the
+corresponding suboptions Map to the OptionObjectFactory, it could use OptionFramework
+to take care of it. It is unclear, what other problems can arise.</emph>
+</p>
