Hello!
Recently I have been working on compiling the JOnAS test suite
with cacao and I found a problem in the implementation of
getBootPackages: When getResources returnes an endores jar before
glibj.zip and this jar has a META-INF/INDEX.LIST, getBootPackages
tries to pull the boot packages only from this (first) jar.
I changed the VMClassLoader.java of cacao to read all the resources.
The patch is appended below. Caution: As my Java skills are practically
non-existant this may be a bad solution. It worked for me. I used
a quick-and-dirty script to add INDEX.LIST to glibj.zip (available on
http://c1.complang.tuwien.ac.at/cacaowiki/BootPackages
) and with the patch to cacao the JOnAS genic tool finally worked.
You may want to make a similar change to the reference implementation
of getBootPackages.
