OK, after a bit of experimentation I've now got things running, so
just in case anyone's interested here's what I had to do. Recompile
the kernel, with the only change from GENERIC being an options MAXDSIZ
line:

options MAXDSIZ="2147483648U"

Then once that was built and in place I added the following to ~/.profile:

export CATALINA_OPTS="-Xms128m -Xmx1024m"

ulimit -s 8192
ulimit -d 2040288
ulimit -l 2040288

Following a reboot I'm able to start the webapp, and after a little
light testing it seems to run fine!
