Okay, I see. I was too intent on changing the current chain - problem indeed goes away by just plugging in an entirely new chain.

*edit*

So it looks like I can change the UpdateRequestProcessorChain.chain because its package protected. So I can make a new chain in the test rather than add a config file - but I lose the testing of the parsing of the config settings for the SignatureUpdateProcessor. I suppose I am not so attached them, but I kind of like the idea of some of that hitting a test...no?
