Would be nice if these tests could do a deeper level of validation to see that the certs were translated onto the context rather than just checking that a context was created.  Since it doesn't look like SSLContext has any getters to return the cert info back, I don't see an easy way to do this without mocking or creating a more full-blown test that would stand up a server socket and check that you can connect to it appropriately over SSL.  Maybe it's not worth the effort, just seems like the coverage here is a little thin.
