Thanks a lot for the quick reply! Maybe we should update kaffe to the CVS
version of kjc. Do you have any plans for a release of the next version of

I'm horribly sorry that I've come off so harshly. I've spent the night fighting
with ant 1.6.0 only to fail at what seems to be a compiler bug, and the
frustration about that made me say things I shouldn't have said in such a tone.
Please accept my sincere apologies.

The same thing happens with free software projects driven by volunteers all the
time as well. I unfortunately don't have the time to respond to every bug
report to kaffe either, but fortunately there are a few folks around that take
care that the development goes on without my input. In general I think kaffe
manages to give the impression of things progressing somehow on its mailing

My only real beef with kjc development, is that so little of it is announced to
the public, afaik. So if the mailing list traffic solely consists of bug
reports it gives the wrong impression that the project is dead. 

I'm very glad KJC is not dead, since it (and the tools that come with it) is a
very, very useful tool. I hope you can ignore the harsh tone of my message, and
see it as a PR bug report: you could get a better exposure of your good work,
if you were more public about the good work you're doing. ;)

A good free java-to-bytecode compiler is vital for development of free java
appications. Jikes developement seems to have fallen asleep, and every now and
then, I'm afraid the same would happen to KJC. GCJ is developping at a fast
pace, but it's not useable for compiling other class libraries, than GCJ's. So
basically, we really need you and your business to survive ;)

In this spirit, I wish you, your dearest, your company and your projects a
happy and successful New Year, and I hope you'll accept my apologies.
