<snip good analysis that I didn't read before sending my email>
Assuming that CWindow is a native AWT implementation helper class,
Yup, it's a native peer.
and given that most Cocoa windowing functions must be done from the
AppKit thread,
For all practical purposes, "most" == "all", unfortunately :(
I'm guessing that CWindow has queued the setFrame operation up for
the AppKit thread to perform, and is awaiting completion.
The AppKit thread has CWindow trying to execute the queued operations
from Java. It's holding a native lock while doing so, and
(unfortunately) also trying to ask Java about some state, which
requires grabbing the AWTTreeLock.
The AWT EventThread has CWindow trying to put an operation on the
queue... which requires grabbing the native lock. Of course, the AWT
EventThread is holding onto the AWTTreeLock...
I would say that this is Apple's bug
Yup.
and that they probably didn't intend to attempt to acquire the
AWTTreeLock from the AppKit thread.
Yup.
I do not envy them the task of interfacing the Swing API to AppKit.
Ohhh... the stories I could tell :)
I would love it if Apple could change the implementation
architecture so that the AppKit thread *is* the AWT Event Dispatch
Thread, but I'm sure that they had good reasons for separating them.
1. Not everything happens on the AWT-EDT. Until very recently, AWT
operations were allowed from any thread, and many many badly written
Swing apps do lots from the wrong thread.
2. Lots of badly written Java apps block the EDT for totally insane
things... like network access.
3. It's possible (and not uncommon) to have multiple EDTs - Applets,
for instance.

Q: WILL SOMEONE PLEASE EXPLAIN HOW WE GOT FROM GOD TO STRIP BOWLING???
A: Well, we were talking about God, and his Love for everyone being
equal.
It's pretty simple to go from that concept to the concept that God loves
everything equally as well (actually, that might be why abandoned ideas
tend to resurface periodically - God is paying attention, even if no one
else is). Sports have got to fall into that category, and so if anyone
anywhere has ever played strip bowling, the idea is a permanent part
of our
consciousness (our gestalt). Be honored that you have been chosen for
this
monumental task.
