There is a library called rtxt-VersionNum that makes my serial port work 
great with drivewrire.  I believe it is now part of Aaron's drivewire4 java 
packages.  Yes, from my dw4-4.3.0 install:

I believe it auto chooses after detecting the local architecture.

On the PI you may have to hard code it in the startup, or maybe even find a 
version built for the arm. It has been around for a while but I don't 
really know if there is am ARM build.

512k isn't very much ram though, so good luck.
