AppContext issue in Apple Java 6 -- same issue in Oracle Java 7?

[James Tomson]

Hello,

We've been experiencing lockup issues with our Java Web Start application
on MacOSX since the introduction of 7u25. Running with 7u25, our
application is now invoking swing methods on both the AWT-EventQueue owned
by our 'main' thread group, as well as a queue instance owned by a
"javawsApplicationThreadGroup" group.

Now in this situation of dispatching events multiple AWT-EventQueues there
is a risk of deadlock, and in our case we've seen these fairly frequently
with 7u25, which renders our app unresponsive and must be forced quit.

Hopefully this deadlock issue is related to the fix for 6u51 involving
event dispatching with different AppContexts (since it seems a new
AppContext has been introduced in the javawsApplicationThreadGroup?) and
can be applied to 7 as well...

Cheers,
James

them are about Apple Java. There are one or two links where people are
reporting 7u25 causing troubles, however, there is not enough evidence >to
conclude that it is the same problem as with Apple Java.
