Full problem description:

The program contains a single thread that attaches and detaches from JNI in a loop.
The loop-count and the sleep-time in the loop can be customized via command line arguments.

Test case:
The test progam is JniTest.zip
Compile and Link the Test program
Open the Task Manager in the machine and add the column "Handle" to the list of columns displayed.

Start the test program
Observe the Handle count for the process JNITest.exe
It can be observed that the Handle count increases by two for every execution of the for loop. Each execution consists of one call AttachCurrentThread and DetahCurrentThread to JVM.Open "Process Explorer" from www.sysinternals.com and observe the type of handles used by the process JNITest.exe. It can be seen that the leak happens for the type "Event".
