Hi Jim
One thing we were looking at was trying to make sure that GeoMesa (using
Guava 17 by way of Accumulo) and ElasticGeo (using Guava 18 by way of
Elasticsearch) wouldn't cause conflicts if both extensions were installed.
One suggestion was to try and have each extension run in its own class
loader. However, if we want to have a different version of Guava for these
two dependencies, then we could not have Guava in core GeoServer (else it
would conflict with one of the extensions).
