Are you compiling BioJava from source, or using a binary release?
If a release, then which one? If from source, what did you use
to compile it, and are what JVM version are you running on? Sun
do sometimes manage to break binary compatibility between releases.
Compiling on 1.4 but running on earlier platforms seems to be
the most problematic case.

Not really. That's the format in which method signatures
are encoded in Java .class files. Primative types are encoded
as single letters (I presume 'I' is int, although I don't know
for sure off the top of my head) and object references
are encoding as Lsome/package/MyClass;.
It would be more friendly of the exception handling code to
convert this back to a more human-readable form, but you can't
have everything...
