[Pljava-dev] one static method disappearing when second one is defined?!

I've hit a very weird problem. I'm working on a class that provides
information about the java crypto providers via ResultSetProviders. Code
below. If I comment out the 'listServices()' methods then I can deploy the
jar and run listProviders() without a problem. If I uncomment either
listServices() method then I get an error when running the previously
successful listProviders() call. IMPORTANT: I'm not making any calls to
listServices(), I'm calling a method that I've successfully called before
with an unchanged ddr configuration.

ERROR: Unable to find static method sandbox.Crypto.listProviders with
signature ()Lorg/postgresql/pljava/ResultSetProvider;

I'm not seeing any compiler or postgresql errors and the jar file contains
a Crypto class (although I haven't disassembled it yet). Any ideas?

Thanks,

Bear
