ClassCastException on justice

Run "java -cp .;bcel-5.1.jar org.apache.bcel.verifier.Verifier j00000.class",
where j00000.class is a hand-made class file that contains some errors (that I'm trying to identify).

JustIce ends with a ClassCastException.

The output from the verifier is:

JustIce by Enver Haase, (C) 2001-2002.
