Re: Incorrect Java methods called from CNI

First, are you sure that the CNI .h file you generated for the class you
are calling is consistent with the implementation? If you added a method
to the class (or its superclass) and forgot to regenerate the .h files,
you'll encounter this problem.
I'm not sure what I can provide to help someone track this down short of
the actual library source, but it could be quite awhile before I'd be
able to come up with a small set of code that duplicates the problem,
since I have no idea what might be causing it. If you have any ideas in
the meantime, I'd be happy to provide what I can.
You can run "gcc -S"/"gcj -S" to get a dump of the asm being generated
for the caller method, and the vtable of the callee. Specifically, there
should be a symbol starting with "_ZTVN" in the class being called which
contains the vtable layout.
