Method Detail

canPumpEvent

protected boolean canPumpEvent(AWTEvent event)

Description copied from class: ConditionalEventPump

Returns whether this event can be pumped from the EventQueue. JDK 1.4 introduced SequencedEvent, which is an event holding a list SequencedEvents that should be dispatched in order. Bug #4531693 was caused by the fact that the first SequencedEvent of a list, when dispatched, might end up calling an event listener that displayed a dialog (or called Foxtrot, that uses the same event pumping mechanism); the new event pump might try to dispatch the SequencedEvent second in the list (while the first wasn't completely dispatched yet), causing the application to hang. Bug #4531693 has been fixed in JDK 1.4.2, and backported to 1.4.1, but seems to be sneaking in again in JDK 5 and JDK 6.
