I have a tablet too, but it's a different model.  ImageJ works fine
though.  Unless you have a lot of free memory, disabling swapping is
quite possibly a bad idea.  Have you tried the -Xmx option to set the
memory?  For instance -Xmx500m to allow Java to use 500 megabytes of
RAM.

Does it only fail when you use the stylus or does a mouse fail as
well?  Perhaps there's an issue with your tablet drivers.
