question: public static File createTemporaryAgentJar ( final String agentClass , final String bootClassPath , final boolean canRedefineClasses , final boolean canRetransformClasses , final boolean canSetNativeMethodPrefix ) throws IOException { final File jarFile = File . createTempFile ( "javaagent." + agentClass , ".jar" ) ; jarFile . deleteOnExit ( ) ; createAgentJar ( new FileOutputStream ( jarFile ) , agentClass , bootClassPath , canRedefineClasses , canRetransformClasses , canSetNativeMethodPrefix ) ; return jarFile ; }
target:  Creates a jar in runtime with the proper manifest file to start the javaagent. <p/> This method is convenient to java agent developers since they can test their agents without creating a jar first.
