A DESCRIPTION OF THE PROBLEM :
some times my applicatoin UI will hang up, it's very random. when I put -Xcheck:jni, everytime when the GUI hang, the console keep printing "Warning: Calling other JNI functions in the scope of Get/ReleasePrimitiveArrayCritical or Get/ReleaseStringCritical". it seems the thread is waiting the state. But there is no way to know which thread and which JNI function caused the problem.

below are some log messages, looks like the probelm is occured when call sun.awt.windows.XXXX.
