[Pljava-dev] Stack depth limit exceeded with pljava 1.2.0

I've an extension class with two public static methods, both of which
worked under PL/Java 1.1.0 / PostgreSQL 8.0.3. With PL/Java 1.2.0
and PostgreSQL 8.1.3 one of the methods still works alright, but the
other produces an exception as seen below. Can anyone advise as to
how to debug?

Thanks in advance. Please let me know if you need additional
information.
