[kaffe] Adventures in building JBoss with Kaffe

Hi all,

I decided to start a small JBoss building experiment today, by going 
back in time, and starting with the earliest Jboss release for which I 
could find source [1], trying to build it with anrt and kaffe. Here are 
the results:

JBoss 2.4.3:

bash-2.05a$ tail -f /tmp/topic/orig/2.4.3/build.log.kjc
[snip] 
/var/tmp/topic/orig/2.4.3/jboss/src/main/org/jboss/util/FileURLPatch.java:51: 
error:Cannot find type "sun/net/www/protocol/file/Handler"

Yeah, well, everyone knows you should not use sun.* classes, right? Or 
at least be sane enough not to import them directly. :)

JBoss 2.4.4:

     [javac] 
/var/tmp/topic/orig/JBoss-2.4.4-src/jboss/src/main/org/jboss/util/FileURLPatch.java:51: 
error:Cannot find type "sun/net/www/protocol/file/Handler"

Ahem. On a side note, the ant build uses CVS to check out some stuff 
from the JBoss server. Doesn't make too much sense to me in a released 
source tarball.


JBoss 2.4.9:

It still tries to grab something from the JBoss CVS server, whatever it 
is. It takes half an hour to do it, ao it has improved at least tenfold 
since 2.4.4, which took just a few minutes. It still fails with:

     [javac] 
/var/tmp/topic/orig/JBoss-2.4.9-src/jboss/src/main/org/jboss/util/FileURLPatch.java:51: 
error:Cannot find type "sun/net/www/protocol/file/Handler"


JBoss 3.0.8:

This one fails squarely on kaffe's URL handler handling, somehow.

JBoss 3.2.4:

The build dies early, too, because of a problem with kjc:

Okay, looks like some problem with our Zip code :(

So, I guess the more interesting JBoss builds are from version 3 on, 
since earlier it seems to use some really ugly sun.* classes, that no 
free platform can implement. It's still a widely used practice in JBoss 
3.0.8, unfortunately, so it's probably impossible to build JBoss 3.0.8 
on a free runtime. Finally, I've also looked at 3.2.4, which also 
imports sun classes, but much less, only from the somewhat documented as 
part of JSSE com.sun.net.ssl package, and of course the classical 
mistake, sun's Base64 encoder[2].

[1] Forget the JBoss download page, and go straight to 
http://sourceforge.net/project/showfiles.php?group_id=22866 to get all 
files.
[2] Why people still use that in 2004 is beyound me. jakarta commons 
codec has been there for years now.
