<AWT Dev> [11][JDK-8152974] AWT hang occurs when sequenced events

[Krishna Addepalli]

Hi Sergey,

The event is present, but with the id "java.awt.event.FocusEvent.FOCUS_LAST+1", whereas when it is pumping the events, it is looking for "java.awt.event.FocusEvent.FOCUS_LAST+2", which is not in the queue.

Thanks,
Krishna

This is what is leading to the hang.

But both events are posted by the test, why the second event is not present in the queue?
