Github user mike-tr-adamson commented on the issue: https://github.com/apache/tinkerpop/pull/534 I'm concerned about changing the `getMechanism` logic based on the failing tests. The tests can legitimately fail both ways. It would be valid to fix those tests so that they can fail on either a `ResponseException` or a `GSSException`. As has already been said the difference in error being whether the test finds any kerberos configuration that it can use. The tests were failing on my machine for exactly the same reason - I had an `/etc/krb5.conf` file. I'm not that hung up on the change because you have to provide a `JAAS_ENTRY` in order to use kerberos. It's more of a principal thing. The tests were failing on my machine prior to this PR so the failure was not related to any of these changes. As such they could be fixed outside of this PR in which case the `getMechanism` change wouldn't be needed.
