-/**
- * This package contains annotations and enumerations that are used to
- * add DTrace-specific information to a tracing provider.
- * <p>
- * The DTrace-specific annotations modify the attributes of a DTrace provider
- * implementation when it is used by the tracing subsystem.  The annotations are
- * added to a {@code com.sun.tracing} provider specification to control
- * specific attributes of the provider as it relates to DTrace.
- * <p>
- * Any other tracing subsystems supported by the system will ignore these
- * annotations.
- * <p>
- * DTrace probes have additional fields and stability attributes that are
- * not accounted for in the generic tracing package.  If unspecified, the
- * default values are used for the stability and dependency attributes of
- * probes, as well as for the module and field names of the generated probes.
- * The values can be specified by adding the appropriate annotations to the
- * provider specification.
- * <p>
- * The {@code FunctionName} annotation is used to annotate the tracepoint
- * methods defined in the provider specification.  The value of this annotation
- * is used as the {@code function} field in the generated DTrace probes. It
- * is typically set to the name of the enclosing function where the
- * tracepoint is triggered.
- * <p>
- * The {@code ModuleName} annotation is used to annotate the provider
- * specification itself and applies to all the probes in the provider.  It
- * sets the value of the {@code module} field in the generated DTrace probes.
- * <p>
- * The remaining annotations, are also applied to the provider itself, and
- * are used to set the stability and dependency attributes of all probes in
- * that provider.  Each probe field and the probe arguments can be
- * independently assigned interface attributes to control the stability
- * ratings of the probes.
- * <p>
- * Here is an example of how to declare a provider, specifying additional DTrace
- * data:
-<PRE>
-    &#064;ProviderName("my_app_provider")
-    &#064;ModuleName("app.jar")
-    &#064;ProviderAttributes(&#064;Attributes={
-        name=StabilityLevel.STABLE,data=StabilityLevel.STABLE,
-        dependency=DependencyClass.COMMON})
-    &#064;ProbeAttributes(&#064;Attributes={
-        name=StabilityLevel.STABLE,data=StabilityLevel.STABLE,
-        dependency=DependencyClass.COMMON})
-    &#064;ModuleAttributes(&#064;Attributes={name=StabilityLevel.UNSTABLE})
-    public class MyProvider {

-/**
- * This package provides a mechanism for defining and
- * inserting tracepoints into Java-technology based applications, which
- * can then be monitored by the tracing tools available on the system.
- * <p>
- * To add tracepoints to a program, you must first decide where to place the
- * tracepoints, what the logical names are for these points, what information
- * will be available to the tracing mechanisms at each point, and decide upon
- * any logical grouping.
- * <p>
- * You add instrumentation to a program in three steps:
- * <ul>
- * <li>First, declare tracepoints by creating interfaces to define
- * them, and include these interfaces in the program definition.
- * The declared interfaces are standard Java technology-based
- * interfaces and are compiled with the program.</li>
- * <li>Second, add code in the application to create an instance of the
- * interface at some point during the initialization of the application,
- * using a factory class provided by the system. The reference to the
- * instance can be stored as a global static, or passed as context to all
- * the places where it is needed.</li>
- * <li>Finally, add the actual tracepoints to the desired locations in the
- * application by inserting a call to one of the methods defined in the
- * interface, via the factory-created reference.</li>
- * </ul>
- * <p>
- * The method calls representing the tracepoints have no logical
- * impact on the program.  The side effect of the call is that any
- * activated tracing mechanisms will be notified that the tracepoint has
- * been hit, and will take whatever actions are appropriate (for example,
- * logging  the tracepoint, or triggering a DTrace probe, etc.).  In most
- * cases, the impact on performance of adding tracepoints to the application
- * will be minimal.
- * <p>
- * Each logical grouping of tracepoints should be defined in a common
- * interface, called a <i>provider</i>.  An application can have one or many
- * providers.  Each provider is independent and can be created whenever
- * it is appropriate for that provider, for example, when a subsytem is
- * initialized.  Providers should be disposed of when they are no longer
- * needed, to free up any associated system resources.  Each tracepoint
- * in a provider is represented by a method in that interface.  These methods
- * are referred to as <i>probes</i>.  The method signature determines the probe
- * parameters.  A call to the method with the specified parameters triggers
- * the probe and makes its parameter values visible to any associated tracing
- * mechanism.
- * <p>
- * User-defined interfaces which represent providers must extend the
- * {@code Provider} interface.  To activate the system-defined
- * tracing mechanisms, you must obtain an instance of the
- * {@code ProviderFactory} class, and pass the class of the provider to
- * the {@code createProvider()} method.  The returned instance is then used to
- * trigger the probes later in the application.
- * <p>
- * In addition to triggering the probes, the provider instance can be used
- * to obtain direct references to the {@code Probe} objects, which can be used
- * directly for triggering, or can be queried to determine whether the probe is
- * currently being traced.  The {@code Provider} interface also defines a
- * {@code Provider.dispose()} method which is used to free up any resources
- * that might be associated with that provider.
- * <p>
- * When a probe is triggered, any activated tracing system will be given
- * the provider name, the probe name, and the values of the probe arguments.
- * The tracing system is free to consume this data is whatever way is
- * appropriate.
- * By default, the provider name is the same as the class name of the interface
- * that defines the provider. Similarly, the probe name is
- * the name of the method that defines the probe. These default values
- * can be over-ridden by annotations.  The provider definition can be
- * annotated with the {@code @ProviderName} annotation, whose value will
- * indicate the provider name that the tracing system will use.  Similarly,
- * the {@code @ProbeName} annotation annotates a declared method and
- * indicates the probe name that should be used in the place of the
- * method name.  These annotations can be used to define providers and
- * probes with the same name, in cases where the semantics of the Java language
- * may prevent this.
- * <p>
- * Here is a very small and simple usage example:
- * <p>
- *
-<PRE>
-   import com.sun.tracing.Provider;
-   import com.sun.tracing.ProviderFactory;
-
-   interface MyProvider extends Provider {
-       void startProbe();
-       void finishProbe(int value);
-   }
-
-   public class MyApplication {
-       public static void main(String argv[]) {
-           ProviderFactory factory = ProviderFactory.getDefaultFactory();
-           MyProvider trace = factory.createProvider(MyProvider.class);
-
-           trace.startProbe();
-           int result = foo();
-           trace.finishProbe(result);
-
-           trace.dispose();
-       }
-   }
-</PRE>
- * <p>
- * The Java Development Kit (JDK) currently only includes one system-defined
- * tracing framework: DTrace. DTrace is enabled automatically whenever an
- * application is run on a system and a JDK release that supports it. When
- * DTrace is enabled, probes are made available for listing and matching by
- * DTrace scripts as soon as the provider is created. At the tracepoint, an
- * associated DTrace script is informed of the creation of the provider, and
- * it takes whatever action it is designed to take. Tracepoints in the
- * program have the following DTrace probe names:<br>
- *   {@code <provider><pid>:<module>:<function>:<probe>}
- * Where:
- * <ul>
- * <li>{@code <provider>} the provider name as specified by the application</li>
- * <li>{@code <pid>} the operating system process ID</li>
- * <li>{@code <module>} undefined, unless specified by the application</li>
- * <li>{@code <function>} undefined, unless specified by the application</li>
- * <li>{@code <probe>} the probe name as specified by the application</li>
- * </ul>
- * <p>
- * The {@code com.sun.tracing.dtrace} package contains additional
- * annotations that can be used to control the names used for the
- * <code>module</code> and <code>function</code> fields, as well as annotations
- * that can be added to the provider to control probe stability and dependency
- * attributes.
- * <p>
- * Integer, float and string probe parameters are made available to DTrace
- * using
- * the built-in argument variables, {@code arg0 ... arg_n}.  Integer-types
- * are passed by value (boxed values are unboxed), floating-point types are
- * passed as encoded integer
- * arguments, and {@code java.lang.String} objects are converted
- * to UTF8 strings, so they can be read into the DTrace script using the
- * {@code copyinstr()} intrinsic.  Non-string and non-boxed primitive
- * reference arguments are only
- * placeholders and have no value.
- * <p>
- * Using the example above, with a theoretical process ID of 123, these are
- * the probes that can be traced from DTrace:
-<PRE>
-    MyProvider123:::startProbe
-    MyProvider123:::finishProbe
-</PRE>
- * When {@code finishProbe} executes, {@code arg0} will contain the
- * value of {@code result}.
- * <p>
- * The DTrace tracing mechanism is enabled for all providers, apart from in the
- * following circumstances:
- * <ul>
- * <li>DTrace is not supported on the underlying system.</li>
- * <li>The property {@code com.sun.tracing.dtrace} is set to "disable".</li>
- * <li>The RuntimePermission {@code com.sun.tracing.dtrace.createProvider}
- * is denied to the process.</li>
- * </ul>
- * <p>

-/**
- * This package contains internal common code for implementing tracing
- * frameworks, and defined a number of existing frameworks.
- * <p>
- * There are four tracing frameworks currently defined.  The "Null" and
- * "Multiplex" frameworks are used internally as part of the implementation.
- * The "DTrace" framework is the prime consumer framework at the moment,
- * while the "PrintStream" framework is a functional, but hidden, framework
- * which can be used to track probe firings.  All but the "DTrace" framework
- * are defined in this package.  The "DTrace" framework is implemented in the
- * {@code sun.tracing.dtrace} package.
- * <p>
- * This package also contains the {@code ProviderSkeleton} class, which
- * holds most of the common code needed for implementing frameworks.
- * <p>
- * The "Null" framework is used when there are no other active frameworks.
- * It accomplishes absolutely nothing and is merely a placeholder so that
- * the application can call the tracing routines without error.
- * <p>
- * The "Multiplex" framework is used when there are multiple active frameworks.
- * It is initialized with the framework factories and create providers and
- * probes that dispatch to each active framework in turn.
- * <p>
- * The "PrintStream" framework is currently a debugging framework which
- * dispatches trace calls to a user-defined PrintStream class, defined by
- * a property.  It may some day be opened up to general use.
- * <p>
- * See the {@code sun.tracing.dtrace} and {@code com.sun.tracing.dtrace}
- * packages for information on the "DTrace" framework.
