This is kind of annoying because GWT fails to build with the newer JDKs due
to the issue mentioned before with the change to generics.  So it's a two
step workaround:  Use the older sun JDK to compile the classes & after it
crashes, use run ant again with the newer JDK so that the GWT compiler
doesn't crash the VM.

This also happens if I try to use the older JDK with my projects, but that's
not really an issue since I just use the latest OpenJDK in the Ubuntu
repos.

Might be relevant that I'm using 64-bit jdks.
