Why would ConfigurationService.get(XMLObjectProviderRegistry.class) return null ?

Nothing is being done in the test to ensure that OpenSAML is
initialized.  If you run the test alone, it's absolutely always going to
fail.  If you run it as part of many tests in a suite, then it may or
may not succeed depending on whether some other test has previously run
that inited OpenSAML. 

The best way to fix is to just have it extend OpenSAMLInitBaseTestCase,
which is just a simple base class with a @BeforeSuite that inits OpenSAML.

This is in general a requirement for any test that needs OpenSAML to be
initialized before it can run.
