> Key: TINKERPOP-1830
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1830
> Project: TinkerPop
> Issue Type: Bug
> Components: tinkergraph
> Affects Versions: 3.3.0, 3.2.6
> Reporter: Michael Pollmeier
> Assignee: Michael Pollmeier
> Priority: Minor
> Fix For: 3.2.7, 3.3.1

>
> My colleage Fabian Yamaguchi <[email protected]> discovered a race condition
> in tinkergraph's index creation. He fixed it by simply replacing
> `parallelStream` with `stream`. Quoting his analysis:
> > So, reading the code, you see that this.put is called in parallel, but that
> > method seems to contain a race as get is called on the index, checked for
> > null, and a subsequent write is performed. It still seems like using stream
> > here fixes the problem we've been seeing, and the performance hit is not
> > significant.
