Thank you very much for following up, Mark. I'm using OpenJDK build 1.6.0-b09 -
unfortunately I can't tell which is the output of rpm since I'm testing openjdk
with Ubuntu - I don't have a Fedora box at hand right now.

I was confused too as I saw that one of the bugs has been fixed time ago - I
suspect it could be a similar bug, but slightly different. I'm working to get a
stack trace and post to the issue list at launchpad.

May I ask another thing? I've also run a few performance benchmarks side-by-side
with Sun's JDK 6 on Ubuntu, and OpenJDK seems to be really really slower, at the
point that I think I'm doing something wrong. I'll post in a few hours my
findings on my blog, but in the meantime is there anything I should know, such
as special command line switches etc? AFAIK OpenJDK runs the same HotSpot
compiler than Sun's JDK 6, or am I wrong?

Thanks.
