[macosx] Java 7 print dialog creates a new window on app-switch.

[Petr Pchelko]

Hello, Abhinay.

The bug probably duplicated the following issue: http://bugs.sun.com/view_bug.do?bug_id=8005997

The issue is fixed in jdk 8, however it was not yet back ported to jdk7 updates.

With best regards. Petr.
