-/**
- * This class is intended to be a central place for the jdk to

- * of startTime, as well as a general
- * mechanism of setting arbitrary times in an array.
- * All unreserved times in the array can be used by callers
- * in application-defined situations. The caller is responsible
- * for setting and getting all times and for doing whatever
- * analysis is interesting; this class is merely a central container
- * for those timing values.
- * Note that, due to the variables in this class being static,
- * use of particular time values by multiple applets will cause
- * confusing results. For example, if plugin runs two applets
- * simultaneously, the initTime for those applets will collide
- * and the results may be undefined.
- * <P>
- * To automatically track startup performance in an app or applet,
- * use the command-line parameter sun.perflog as follows:<BR>
- * <pre>{@code
- * -Dsun.perflog[=file:<filename>]
- * }</pre>
- * <BR>
- * where simply using the parameter with no value will enable output
- * to the console and a value of "{@code file:<filename>}" will cause
- * that given filename to be created and used for all output.
- * <P>
- * By default, times are measured using System.currentTimeMillis(). To use
- * System.nanoTime() instead, add the command-line parameter:<BR>
- -Dsun.perflog.nano=true
- * <BR>
- * <P>
- * <B>Warning: Use at your own risk!</B>
- * This class is intended for internal testing
- * purposes only and may be removed at any time. More
- * permanent monitoring and profiling APIs are expected to be
- * developed for future releases and this class will cease to
- * exist once those APIs are in place.

+/**
+ * This class is intended to be a central place for the jdk to
+ * log timing events of interest. There is pre-defined event
+ * of startTime, as well as a general
+ * mechanism of setting arbitrary times in an array.
+ * All unreserved times in the array can be used by callers
+ * in application-defined situations. The caller is responsible
+ * for setting and getting all times and for doing whatever
+ * analysis is interesting; this class is merely a central container
+ * for those timing values.
+ * Note that, due to the variables in this class being static,
+ * use of particular time values by multiple applets will cause
+ * confusing results. For example, if plugin runs two applets
+ * simultaneously, the initTime for those applets will collide
+ * and the results may be undefined.
+ * <P>
+ * To automatically track startup performance in an app or applet,
+ * use the command-line parameter sun.perflog as follows:<BR>
+ * <pre>{@code
+ * -Dsun.perflog[=file:<filename>]
+ * }</pre>
+ * <BR>
+ * where simply using the parameter with no value will enable output
+ * to the console and a value of "{@code file:<filename>}" will cause
+ * that given filename to be created and used for all output.
+ * <P>
+ * By default, times are measured using System.currentTimeMillis(). To use
+ * System.nanoTime() instead, add the command-line parameter:<BR>
+ -Dsun.perflog.nano=true
+ * <BR>
+ * <P>
+ * <B>Warning: Use at your own risk!</B>
+ * This class is intended for internal testing
+ * purposes only and may be removed at any time. More
+ * permanent monitoring and profiling APIs are expected to be
+ * developed for future releases and this class will cease to
+ * exist once those APIs are in place.

+<p>The scripting API consists of interfaces and classes that define
+Java™ Scripting Engines and provides
+a framework for their use in Java applications. This API is intended
+for use by application programmers who wish to execute programs
+written in scripting languages in their Java applications. The
+scripting language programs are usually provided by the end-users of
+the applications.
+</p>
+<p>The main areas of functionality of <code>javax.script</code>
+package include
+</p>
+<ol>
+<li><p><b>Script execution</b>: Scripts
+are streams of characters used as sources for programs executed by
+script engines. Script execution uses
+{@link javax.script.ScriptEngine#eval eval} methods of
+{@link javax.script.ScriptEngine ScriptEngine} and methods of the
+{@link javax.script.Invocable Invocable} interface.
+</p>
+<li><p><b>Binding</b>: This facility
+allows Java objects to be exposed to script programs as named
+variables. {@link javax.script.Bindings Bindings} and
+{@link javax.script.ScriptContext ScriptContext}
+classes are used for this purpose.
+</p>
+<li><p><b>Compilation</b>: This
+functionality allows the intermediate code generated by the
+front-end of a script engine to be stored and executed repeatedly.
+This benefits applications that execute the same script multiple
+times. These applications can gain efficiency since the engines'
+front-ends only need to execute once per script rather than once per
+script execution. Note that this functionality is optional and
+script engines may choose not to implement it. Callers need to check
+for availability of the {@link javax.script.Compilable Compilable}
+interface using an <I>instanceof</I> check.
+</p>
+<li><p><b>Invocation</b>: This
+functionality allows the reuse of intermediate code generated by a
+script engine's front-end. Whereas Compilation allows entire scripts
+represented by intermediate code to be re-executed, Invocation
+functionality allows individual procedures/methods in the scripts to
+be re-executed. As in the case with compilation, not all script
+engines are required to provide this facility. Caller has to check
+for {@link javax.script.Invocable Invocable} availability.
+</p>
+<li><p><b>Script engine discovery</b>: Applications
+written to the Scripting API might have specific requirements on
+script engines. Some may require a specific scripting language
+and/or version while others may require a specific implementation
+engine and/or version. Script engines are packaged in a specified
+way so that engines can be discovered at runtime and queried for
+attributes. The Engine discovery mechanism is based on the service-provider
+loading facility described in the {@link java.util.ServiceLoader} class.
