FYI: Make EventQueue.postEvent(null) fail fast

[Mark Wielaard]

Hi,

The following make EventQueue.postEvent() throw a NullPointerException
immediately when it gets a null event.

2004-06-27  Mark Wielaard  <address@hidden>

       * java/awt/EventQueue.java (postEvent): Throw NullPointerException
       when argument is null.

In the past a null event could slip through and only throw a
NullPointerException much later during event processing making debugging
horribly complicated. Committed.

Cheers,

Mark
