I suspect the version of Java you are using is your problem. I am
using JDK 1.1 Beta 3 and it worked fine with the following exceptions:


1.) Several deprecation warnings.


2.) One of the generated java files (ASCII_CharStream.java) was
attempting to call the "void finalize()" method on arrays of
primitives which resulted in the following error:


"ASCII_CharStream.java:36: Can't access protected method finalize in
class java.lang.Object. byte[] is not a subclass of the current class
buffer.finalize();"


Once the invalid attempts to invoke "finalize()" were commented out it
worked fine.
