Actual problem is with libgcj-4.1.1 (which is _not_ listed as a component). See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31332 for a complete description as well as an exemplar Java test case.
Created attachment 151047 [details] Exemplar code Run with "java XMLSetNodeValue".
Created attachment 151048 [details] Stack trace, system profile, and Java system properties.
This works with the gcj that will be in F7.
(In reply to comment #3) Will a patch be released for FC6? (In FC5, there was a bug in libgcj's regex implementation that was never fixed and so we had to recommend/require that users of our software install Sun's JVM when using FC5. Unless FC6's libgcj is fixed, we'll have to recommend the same for FC6.)
(In reply to comment #3) I just ran the exemplar code under FC7 (F-6.91-i386) and it failed with a NullPointerException and produced the same stack trace I previously reported. When FC7 Test 3 is available, I'll re-run the test case. However, I am unable to confirm that this bug has been eliminated under FC7.
I just tested rawhide and this is definitely fixed there. For FC6, I don't know. Are we still doing update for FC6? Anyway it would depend on what the fix actually looks like (I don't know :-)
