Work around bug in the IBM JRE

[GoogleCodeExporter]

There's a bug in the IBM JRE that causes it to return invalid (truncated) 
values from SecretKey.getAlgorithm(), which subsequently causes 
Mac.getInstance() to blow up in Association#sign(). The result is that the 
openid4java library becomes unusable on IBM's WebSphere Application 
Server, among others.

I'm attaching one possible patch, although there are probably more elegant 
ways of going about it. Link to further details:

IBM restricted access to the bug for whatever reason, but here's the text:

Problem:
A getAlgorithm() call on a SecretKey object will return an
abbreviated short name and the
same call on KeyGenerator will return the full name.
