#31 Obfuscator fail with ArrayIndexException

[Alexei Drummond]

I am trying to use your JODE obfuscator code on a JDK1.3.1_01 java project. I get the following
error. Any ideas?

If I preserve all classes JODE works.

When I try to selectively to preserve classes I get the
same error, and earlier on I get a series of:

I seem to get this bug if I don't strip unreachable code
eg:
strip="lvt"
will fail but:
strip="unreach","lvt"
works!
