The Maven application sits on top of the Scala compiler. The Scala compiler is simply JVM byte-code. Any legal byte code (and the Scala byte code is legal, just run the verifier against it) that causes the JVM to crash is of great interest to Sun. Why? Because it is a security vulnerability. Any time that there's an illegal access (like the one that you're reporting), it means that someone could put junk on the stack and cause that junk to be executed as machine code instructions. I have not seen a the JVM blow core (crash) while running anything in a very long time. In any case, if the simple act of compiling Lift caused the JVM to blow up in any sort of reproduceable way, the problem with the JVM would be fixed in very short order (I was in a room full of all the guys that could fix this issue last two weeks ago: http://www.openjdk.org/projects/mlvm/jvmlangsummit/agenda.html).
