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

[Mitch Chapman]

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.
