 * @test
 *
 * @summary converted from VM Testbase nsk/jvmti/SetJNIFunctionTable/setjniftab001.
 * VM Testbase keywords: [quick, jpda, jvmti, noras]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test exercises the JVMTI function SetJNIFunctionTable().
 *     It checks the following spec assertion:
 *         Set the JNI function table in all current and future JNI
 *         environments. As a result, all future JNI calls are directed
 *         to the specified functions.
 *     The test works as follows. Upon redirection of the JNI function
 *     MonitorEnter(), the interception is verified:
 *         - inside a main thread (checking current JNI environment)
 *         - inside new threads attached after the redirection (checking
 *           future JNI environments)
 *         - inside the main thread after detaching and attaching back
 *           (checking future JNI environments)
 *    Finally, the original JNI function table is restored and verified
 *    inside the main thread and new threads.
 * COMMENTS
 *     The test has been changed due to the rfe 4946196. See also evaluation
 *     of the bug 4921979.
