https://github.com/apache/tinkerpop/pull/372
I opened two PRs, (one for tp31 as Stephen requested, and a new one for
master):
* #377 (master)
* #378 (tp31)
As far as I can tell, GraphFilter did not exist in 3.1, and it may not even
be possible to induce the buggy traversal behavior describe in #372 (which was
all based on master / 3.2). The underlying datastructure corruption -- putting
a StarOutEdge into the inEdges map -- does exist on 3.1, and @okram's addEdge
fix applies cleanly on 3.1, but without applyGraphFilter, I'm not sure it even
matters for correctness on 3.1.
