OK. That might explain why some people are not seeing these things. As
far as I know KissMe, SableVM and Orp don't have verifiers at the
moment. Tom Tromey recently added a verifier to gij though. But they
don't use jikes but gcj to compile to class files.

I don't think so. From the package page:
http://packages.debian.org/unstable/devel/jikes.html
you can get at their source diff
http://ftp.debian.org/debian/pool/main/j/jikes/jikes_1.15-0.1.diff.gz
And it only contains one actual patch for NaN values.

That would be very nice to have. But we need a way to check if it solves
the verify errors. I will spend some time tomorrow to see how/if we can
use the gcj verifier for this.

I am aiming to have the release tarball ready on friday.
How much time would you need to get an interim jikes version going?
Anything I can do to help get it ready?
I can generate binaries for GNU/Linux x86 and powerpc.

Cheers,
