[R] Sjava question on MacOS 10.3

I am running R-1.81, apple's JVM installed with OS 10.3.2, and installed
Sjava-0.65.X (a patched version of Sjava for MacOS from Simon Urbanek, which
I know is inherently dangerous, but...).  This version installed fine and
some aspects seem to work as expected.  However, this is one of the examples
and causes R to hang.  Any insights?  What other information should I
provide to make it easier to answer this question?  Finally, is there a
stable version of Sjava for the MacOS 10.3 that I should be using? (See
