We looked at generating different 'profiles' of GNU Classpath every
now and then,
and it turned out to be non-trivial, since there are differences in core library
behavior from SE release to SE release that would be quite hard to maintain
in the same tree, without resorting to a lot of preprocessing. I would imagine
the boundary between SE and ME to be much higher, so that would seem to
me to require a significant amount of non-trivial build logic to accomplish, if
you are after building certifiably compatible ME and SE releases from the same

A simpler project could be to try to make the OpenJDK class library work
with the PhoneME VM.
