@spmallette Yeah, it looks like it happened with the `Merge branch TP32`
commit. If you look
[here](https://github.com/apache/tinkerpop/commit/960fdc11399590280522189b08727e90cd9b629a#diff-822877f6fd92f5cd4b57fa2167f92928R74)
it has `new HttpBasicAuthenticationHandler()` whereas the [previous
commit](https://github.com/apache/tinkerpop/commit/eae4101c5fb7b8b976c5898a12e180ee23e50269#diff-822877f6fd92f5cd4b57fa2167f92928R74)
uses `instantiateAuthenticationHandler(settings.authentication)`
