I think this case will throw IAE when `SSLParameter.setNamedGroups()` is called right? If so, I think you can delete this test (and the one one on line 123) since it is already covered in the NamedGroupsSpec test. Also, this test is coded such that the expected exception is thrown when the TLS handshake is being made in `runClientApplication()`, which is not the case here.

Same comment for the DTLSNamedGroups test.
