Stephen Mallette commented on TINKERPOP-2512:
---------------------------------------------
Thank you for noticing this. i'm curious is gremlin.sh in gremlin-console has a
similar issue. would you like to submit a pull request for a fix? if so, please
target the 3.4-dev branch.
> Duplicate jars in classpath when running gremlin-server.sh

> Key: TINKERPOP-2512
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2512
> Project: TinkerPop
> Issue Type: Bug
> Components: server
> Affects Versions: 3.4.10
> Reporter: Clément
> Priority: Minor
>
> First noticed with [JanusGraph's
> gremlin-server.sh|https://github.com/JanusGraph/janusgraph/blob/v0.5.3/janusgraph-dist/src/assembly/static/bin/gremlin-server.sh]
> but also seems to apply to [TinkerPop's
> gremlin-server.sh|https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/bin/gremlin-server.sh]:
> the Java classpath contains every jar twice.
> I think this is due to the following
> * A {{CP}} variable is built
> ([gremlin-server.sh#L97-L101|https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/bin/gremlin-server.sh#L98-L101])
> * A {{CLASSPATH}} variable is created and assigned CP
> ([gremlin-server.sh#L103|https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/bin/gremlin-server.sh#L103])
> * Java is started with {{-cp $CP:$CLASSPATH}}
> ([gremlin-server.sh#L169|https://github.com/apache/tinkerpop/blob/master/gremlin-server/src/main/bin/gremlin-server.sh#L169],
> gremlin-server.sh#L187, ...)
> Not setting the {{CLASSPATH}} variable or starting java with {{-cp $CP}}
> should be enough.
