And the documented metadata for the TestShib SP does list the GCM ones
first also:

http://www.testshib.org/metadata/testshib-providers.xml

So since the OP has BC loaded as a security provider, it probably in
fact is trying to do GCM.  And if the BC version is <= 1.50 it's
mandatory to set that system property, or else you'll get some error
similar to what he reported.  So that's sounding more likely to be the
cause, actually.
