spmallette opened a new pull request #1240: TINKERPOP-2312 Empty keys to group() should group to null URL: https://github.com/apache/tinkerpop/pull/1240 https://issues.apache.org/jira/browse/TINKERPOP-2312 Basically, this: ```text gremlin> g.V().group().by('age') The property does not exist as the key has no associated value for the provided element: v[3]:age Type ':help' or ':h' for help. Display stack trace? [yN]n ``` now does this: ```text gremlin> g.V().groupCount().by('age') ==>[null:2,32:1,35:1,27:1,29:1] ``` which has its conveniences but also produces a result that would be easier to follow for new users as opposed to the old exception. All tests pass with `docker/build.sh -t -n -i` VOTE +1
