While validating Jre7u13 and Jre7u15 on Mac OS Safari Issue, found some issues.

As soon as a third party window is opened and then closed in our application, App hangs and not able to do any operation.

The issue is happening from Jre7u13 onwards.

Steps to Replicate 3 Issue added in comment field.

 all three issues might be related since in all the cases once a third party window launches, application gets hanged.


Note: The above mentioned issue is not happening for Windows OS. It is happening for Mac / Safari for Jre7u13 and Jre7u15.
