Description
Deadlock at application startup, possibly a regression in 7u4 b18.

Please, see the attached thread dump from NetBeans startup. This has been encountered only recently, running with 7u4 b18.

Please evaluate ASAP for 7u4.

Thanks.

EVALUATION 7122796, which was integrated into 7u4-b06, may potentially have impact here. However, this fix shouldn't affect any "correct" applications, where sun.awt.SunToolkit class initialization is triggered in the main AppContext.

EVALUATION This is not a regression and not Mac OS X specific: this shared code hasn't been conceptually changed for at least a couple of years, so I'm lowering it to P3 and targeting to 8 (7u6 fix will follow). *** (#1 of 2): [ UNSAVED ] ###@###.### I wonder what is the sequence that leads to EventQueue.detachDispatchThread() *** (#2 of 2): [ UNSAVED ] ###@###.###
