With GNU classpath CVS HEAD and jamvm 1.4.2 this throws no exception so
this is fixed in it it seems. Perhaps all the gnu.regexp fixes should be
ported to 4.1?
Cheers,

It's good to know this is fixed in GNU Classpath, but I filed this against
libgcj for a reason. Reopening the bug.

Is this a regression? libgcj should take care that GCC is in super release
mode now.

No, this is no regression. Java is not release critical to GCC so we
should just fix this bug as we fix many other bugs too. Not just
regressions.

But if it unstablizes gcj, it is not worth the fix at least this late in the
game. Also it is time just like fortran to start thinking about allowing for
java to be release critical to GCC (see Mark M.'s email at
http://gcc.gnu.org/ml/fortran/2006-02/msg00095.html ).

------- Comment #7 from tromey at gcc dot gnu dot org 2006-02-08 18:54 -------
The regex changes are unlikely to cause big destabilization for 3 reasons:
* They are pure java
* The regex code has historically been somewhat broken, so we're unlikely
to make the situation worse
* They've been tested in classpath using mauve
I'll look at this a bit. I'm leaning toward including the changes in 4.1
because we've seen more than one application now with regexes that hit
libgcj bugs.
Andrew, I agree with your point in general. We should probably discuss it
in some forum other than a random regex bug report though :-)
