-------------------------------------------
Summary: Gremlin Server Not Properly Reporting Port Conflict
Key: TINKERPOP3-785
URL: https://issues.apache.org/jira/browse/TINKERPOP3-785
Project: TinkerPop 3
Issue Type: Bug
Components: server
Affects Versions: 3.0.0-incubating
Reporter: stephen mallette
Assignee: stephen mallette
Fix For: 3.0.1-incubating
It is possible to start two instances of Gremlin Server where the second
doesn't immediately throw an error and stop. On shutdown of that second server
an exception is thrown because the shutdown future never properly sets the
channel as it completes exceptionally:
