How to debug assert failure in awt.dll?

[Denis Fokin]

Hi Pete,

As a dirty hack, you can just comment out 

    ret = MessageBoxA(NULL, assertMsg, "AWT Assertion Failure",
        MB_YESNO|MB_ICONSTOP|MB_TASKMODAL);

    // if clicked Yes, break into the debugger
    if ( ret == IDYES ) {
        # if defined(_M_IX86)
            _asm { int 3 };
        # else
            DebugBreak();
        # endif
    }
    // otherwise, try to continue execution

from jdk/src/windows/native/sun/windows/awt_Debug.cpp

this prevents showing the MessageBox and breaking into the debugger.

Thank you,
   Denis.
