Now that I've figured out how to get the output from chrome, here it is:

Looks the same, but there have been times in the past when one worked and the other didn't.

Sorry for the re-assignment back and forth. The problem does appear to be in the JNLP classloading code. Re-assigning back to Omair.

Fixed in IcedTea-Web: http://icedtea.classpath.org/hg/icedtea-web/rev/df3cf32781d3

As usual, I'd like to know when I should expect to see the fix in yum updates and how I can recognize it when I do.  I guess the next time I see openjdk in an update I'll try it.  Any estimate?

Hi Donald. The fix will be in F15/rawhide before the beta deadline (29th). As for current Fedora version, we want to let icedtea have a bit of exposure before backporting it to existing stable releases, so I would guess some time in May/early June.

Deepak, I didn't think there was any plan to change existing stable releases and it's something I'd be against.  In about eight months, those releases without IcedTea-Web (F13 + F14) will be dead anyway.

As mentioned in comment 3, this fix is upstream and in newer versions of Fedora. F14 has been EOL'ed and wont be getting any fixes.
