thanks, I'll check in the current jessie javax.* from CVS and remove the 
org.metastatic classes again from the CVS.

Mark Wielaard is the one to talk to.

That could be the --with-upstream-project-name-source=PATH options. It 
would mean hacking a small m4 macro for each --with-source option, that 
an upstream dir in libraries/javalib, with its own directories and 
wrapper scripts for compiler invocation for each upstream project. 
Basically, I think it should be enough to do a

rm ($build_dir)/all-project.files
touch ($build_dir)/all-project.files
for i in src_dir1 scr_dir2 ... do
find $i -name "*.java" >> $(build_dir)/all-project.files ;

Ant ;)

Seriously though, the hard bit above is collecting all the names of java 
files to compile. If we check that information in for each upstream 
package, and regenerate it when developers/autogen.sh is invoked, I 
don't see a problem.

That's what the change I proposed in kaffe.in in my last e-mail was 
about, without explicitely using an ext directory. It relied in 
install-jar to copy the jar to the apropriat elocation, and would pick 
up all the jars in the directory it considers O.K.
