Unfortunately not. Here is the trace.
Apparently I'm reading it wrong:
"TimerQueue" daemon prio=3D5 tid=3D0x0816cc00 nid=3D0x8403800 in Object.wai=
t() [bf822000..bf822d00]
at java.lang.Object.wait(Native Method)
- waiting on <0x2d04d7c8> (a javax.swing.TimerQueue)
at javax.swing.TimerQueue.run(TimerQueue.java:231)
- locked <0x2d04d7c8> (a javax.swing.TimerQueue)
at java.lang.Thread.run(Thread.java:534)
This seem like a deadlock to me, because it has 0x2d04d7c8 locked but it
is also waiting for it. However if this is truel the trace is full of deadl=
ocks.
