Just undoing [this
commit](https://github.com/apache/tinkerpop/pull/534/commits/62648242c6576b020d2dd2933b89b9d69e87fed0)
in TINKERPOP-1566 and merging in TINKERPOP-1600 does not work for me, see
below. I did not dig in yet, maybe you recognize what is happening. Other tests
without serializeResultToString configured fail the same way. Btw, in my
testing branch I renamed GremlinServerAuthKrb5IntegrateTest to
GremlinServerAuthKrb5Test for faster testing.
