Great!

Well, anything is possible! Somebody once had gcj-built apps running on
a LegoMindstorm with only 32k RAM. Of course, they did this by
completely replacing the runtime library with a very limited tiny
version.
Back in the early days we had little apps running in ~500k (text and
data) on an embedded MIPS platform. I think the easiest way to get
there again is to start stripping functionality out from libgcj. I
would start by eyeballing linker maps to see if there are any obviously
large chunks that can be removed for your application.
