/**
* The test exercises the JVMTI function SetJNIFunctionTable().
* It checks the following spec assertion:<br>
* <code>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.</code>
* <p>
* The test works as follows. Upon redirection of the JNI function
* MonitorEnter(), the interception is verified:
* <li>inside a main thread (checking current JNI environment)
* <li>inside new threads attached after the redirection (checking future
* JNI environments)
* <li>inside the main thread after detaching and attaching back
* (checking future JNI environments)<br>
* Finally, the original JNI function table is restored and verified
* inside the main thread and new threads.
