HOW TO REPRODUCE ON THE RI

It does not appear under HotSpot by a lucky accidence.

ROOT CAUSE ANALYSIS:

The native method Java_sun_awt_windows_WToolkit_isProtectedMode() introduced in version 1.6.0_02, uses the IEIsProtectedModeProcessFunc winapi function declaring it as

   typedef HRESULT IEIsProtectedModeProcessFunc(BOOL *);

It effectively means that the function will be called with the C (cdecl) calling convension whereas it's actually coded with the stdcall calling convension.

As a result, a call to the function breaks stack balance and provokes various unpredictable crashes.

See "Suggested fix" for more information how to fix the problem.
