Re: Neo4j test failures

[Stephen Mallette <sp...@gmail.com>]

yes - u20 i think is a bad one.  an enforcer update might be nice.  I think
versions before u20 will work, but there were certain bug fixes after u20
that were important - the enforcer plugin should probably be at u25 as the
oldest to support given this post in gremlin-users:

as for problems with neo4j, i'm not having any on ubuntu as of this morning
with:

$mvn -version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.8.0_40, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-oracle/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-46-generic", arch: "amd64", family:
"unix"

I'm also not familiar with that specific error.....not sure what that is
offhand.
