[classlib][awt] Can't start any AWT app after recent(9/9/06-11/9/06) changes in java.awt
Hi all!
After checking out the latest classlib from SVN I get this NPE on any
AWT app start:
java.lang.NullPointerException
at java.awt.ToolkitImpl.getSystemEventQueueImpl(ToolkitImpl.java:525)
at java.awt.EventDispatchThread.runModalLoop(EventDispatchThread.java:58)
at java.awt.EventDispatchThread.run(EventDispatchThread.java:47)
Tried both with DRLVM and IBM j9 on Windows.
Anybody has the same problem?
I'll try to investigate it, but maybe somebody has an idea of what's going on?

Of course, I'll remove the confusing variable...

If variable is not used later in the code probably it will be better
just to call constructor? Without assigning the value to the
variable...

I've already found the cause of the problem.
In short: creation of system EventQueue was commented out
in Toolkit constructor because of "the local variable is never read"
compiler warning :)
Variable itself is indeed not used, but the constructor call has some important
side effects...
Will file a JIRA and offer a patch:)
