Replying to my own post...
I just tried this on a Java 1.7 machine and instead of OutOfMemoryError, I
get this:
Exception in thread "main" java.lang.reflect.GenericSignatureFormatError

This is using:
java version "1.7.0_09"
OpenJDK Runtime Environment (IcedTea7 2.3.3) (suse-3.16.1-x86_64)
OpenJDK 64-Bit Server VM (build 23.2-b09, mixed mode)
So it appears that Java seems to think this is an AspectJ bug.
Thanks,
