Comments
EVALUATION The problem is a duplicate of 6542975. We have a prototype fix for 6542975. I built a jre with that fix and provided it to the submitter to verify reproducibility. The submitter confirmed that the bug is not reproducible. Also, this is not a regression as the problem has presented in the code long ago but it hasn't been seen.

EVALUATION The crash in the bug description is consistently from the comctrl32.dll which is called from awt.dll. So most likely it is an AWT bug or a bug inside Microsoft libraries. Further tracing back indicates that JRE 7 b02 is the first one showing the crash. JRE 7 b01 doesn't have the crash. Swapping out jvm.dll of JRE 7 b02 with the b01 VM doesn't fix the crash. On the other hand, using jvm.dll of JRE 7 b02 with JRE 7 b01 doesn't make JRE7 b01 crash. Both experiments indicate that VM is not the source of problem. Reassign to AWT for further investigation.
