Well, for the size it might help stop including all the precompiled *.class/*.jar
files in the repository, that is roughly half of libjava/, and only
configuring java if everything is there to set up building the class files
from source.  We are doing that for years on redhat branches (with the main
intent to avoid just relying on binary blobs, but size reduction is a nice

I think all the prebuilt binary blobs (and generated headers) were added
because java was an --enable-languages=all language and the maintainers
didn't want to add burden of other prerequisities.  But, if we make it that
java will not be configured unless you have those prerequisities, I don't
see why we would need to include those.  For cross-compilers of course
one will need the ecj jar file (target independent) and some java
interpreter around, but it will be needed on the build box.
