I'm using scalaxb to generate Scala code from an XSD. (In particular I am using the maven scalaxb plugin.) The code generation phase runs without a hitch, and eyeballing them, the generated scala files look good. But when I try to compile I am getting a stack overflow on:

The xsd I am using has been tested and works with jaxb.
Scala version is 2.9.0-1, scalaxb is 0.6.2.
So, according to the OP, the problem was resolved by putting -Xss2048k in the jvmArg.
