Java JNA WindowProc JVM Crash

In a previous question I wanted to implement the WndProc to handle the WM_DEVICECHANGE message in order to know when my USB device is attached or detached.

I managed to solve this issue, but .... in some cases the JVM crashes with the followin ugly error message:

    A fatal error has been detected by the Java Runtime Environment:

      EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x1000cb77, pid=3448, tid=4432

     JRE version: 6.0_17-b04
     Java VM: Java HotSpot(TM) Client VM (14.3-b01 mixed mode, sharing windows-x86 )
     Problematic frame:
     C  0x开发者_如何学编程1000cb77

     If you would like to submit a bug report, please visit:

     The crash happened outside the Java Virtual Machine in native code.
     See problematic frame for where to report the bug.

I found that it only crashes the JVM if I close my frame quickly after inserting my USB device, so probably the message isn't handled properly. In the error message it says that there is a "problematic frame", so probably my hidden static window, that handles the WM_DEVICECHANGE message causes the crash, but I'm not sure.

So my question is what can be done in this situation, or what could cause the JVM crash. Any suggestions are welcome.

The problematic frame refers to a stack frame (i.e. a running method). It does not refer to a window (java.awt.Frame or javax.swing.JFrame).

Does closing your window somehow interact with the JNI code?
