As a result, all future JNI calls are directed 36 * to the specified functions. 37 * The test works as follows. Upon redirection of the JNI function 38 * MonitorEnter(), the interception is verified: 39 * - inside a main thread (checking current JNI environment) 40 * - inside new threads attached after the redirection (checking 41 * future JNI environments) 42 * - inside the main thread after detaching and attaching back 43 * (checking future JNI environments) 44 * Finally, the original JNI function table is restored and verified 45 * inside the main thread and new threads. 46 * COMMENTS 47 * The test has been changed due to the rfe 4946196.
