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.
