Research direction
Start by rerunning the Cassandra job with `-Dtest=**/graphdb/thrift/*` and inspect `JanusGraphTest.testVertexTTLImplicitKey` at line 5772, reported through `ThriftGraphTest`. Compare the flaky failure with a successful run to identify the source of the NullPointer; done means the test runs reliably without that error.
