EVALUATION

Unable to reproduce using suggested source code since it's not complete.
It would very useful to know more about the crash Java_sun_awt_Win32GraphicsConfig_getBounds(). Might be useful to look into log generated by IE. I've looked through the bugs and found something that might cause this crash - 4947550. Not sure that this is correct one. Asking submitter for more info.

The crash happens on AwtDropTarget destruction which happens _after_ toolkit disposal due to a dangling COM reference. Suggested fix is considering the destructor an entry point and checking if the toolkit is still active.
