Sorry for the delay. I really don't have an excuse.

The FSF paperwork is required to submit code to the Free Software
Foundation.
I will email you off list and the clerk at the FSF so we can get this
moving.

You can email me the diff and screen capture directly. Then add yourself to

http://wiki.rtems.org/wiki/index.php/RTEMSSummerOfCode#Students_Proposals

getting
boehm-gc working on RTEMS. boehm-gc supports a number of architectures
but has
to be tailored to the OS environment. You will have to pick one architecture
(probably x86) to do the initial port to. On this first target architecture,
you will need to get far enough to get decent test results. Then we try to
repeat on the other architectures boehm-gc supports (and you fix porting
issues
in it)

This means building and testing gcc. There are scripts in rtems-testing/
which are used to test C, C++, Ada, and (preliminary) Objective-C on RTEMS.
You will be augmenting those scripts and then fixing whatever is
required in
gcc to make GCJ work.

This is similar to the GSoC project last year which ported Go to RTEMS. The
student who did that make a list of known issues that had to be addressed.
I will ask him if he is in a position to provide advice.

Start writing the proposal and ask questions.
