Proposal for a Google summer of code project for the Java frontend.

Hello, Ramon

As I told you, I am working with the Java frontend. Currently I am
working with the code from http://llvm.org/svn/llvm-project/java/. The
first task has been to put it up to date, since it was written for
LLVM 1.9 and there are few incompatibilities. This is mostly done. How
can I submit a patch?

Just post the patch into llvm-commits mailing list.

I am interested to get this work funded by a Google summer of code
grant. Is there anyone interested in mentoring this project? Would be
the LLVM interested in it?

Definitely yes, please submit your application as usual.
