The test comment, I assume related to NoClassDefFoundError, is // Caused by VM trying to throw java.lang.InvalidClassException (there's one in java.io instead), which is confusing since there doesn't appear to be a java.lang.InvalidClassException, not sure why the VM would attempt to throw it. Sounds like a Hotspot bug.
