RE: T5 on JDK 1.6 or newer
We moved our production app Savila from JDK 1.6 back to 1.5. That's now more
than a week ago. Since we did no further hangs have shown up.
Unfortunately I have not been able to investigate any further due to time
constraints (the client project). But I'm planning on following the
suggestions some people have suggested here.
Joel, thanks for mentioning my blog. Say "hi' to Josh ;-)

Hi Stephan
Thanks for posted this, you have saved a lot of time for me,
unfortunately for me though I can't go back to JVM 1.5

Unfortunately yesterday we had to switch back to JVM 1.5, as the same
symptoms have shown up again. Seems that there is still a problem and JVM
1.6. update 2 is not the solution.

Although this is really not a good way to investigate a bug (lack of time), I
still want to report that our application has been running fine since
upgrading to "JVM 6 update 2". So it seems that it was the JVM bug Howard
mentioned before and it is indeed fixed. If it shows up again, I'll post
about it.
