> Key: TINKERPOP-1252
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1252
> Project: TinkerPop
> Issue Type: Bug
> Components: neo4j
> Affects Versions: 3.1.1-incubating, 3.2.0-incubating
> Reporter: Geoff Reedy
> Assignee: stephen mallette
> Priority: Blocker
> Fix For: 3.2.0-incubating, 3.1.2-incubating
>
>
> For some transaction conflicts Neo4j will throw a DeadlockDetectedException
> from neo4japi.Neo4jTx#close(). When this happens, the thread that suffered
> this problem may experience a NotInTransactionException on any further
> attempts to interact with the graph
> The problem starts when the abnormal termination of neo4japi.Neo4jTx#close()
> prevents tp3.Neo4jTransaction's threadLocalTx.remove() from being called. The
> calling thread is now associated with a closed neo4japi.Neo4jTx. Now
> tinkerpop believes that the thread already has an open transaction but neo4j
> considers it to be closed.
> I've marked as blocker since there isn't any way to work around the problem
> once it has occurred. I know that a code freeze for 3.2.0 is in effect now or
> shortly, but hopefully it can be thawed enough to put this in.
> The fix is simple and expect to see a pull request shortly.
