   The Travis errors are interesting; the tests run OOM. I got a heap dump and saw that ~78% of the heap is being used by org.apache.maven.plugin.surefire.report.WrappedReportEntry objects. It sounds like https://issues.apache.org/jira/browse/SUREFIRE-1147. It seems like there are too many tests now for surefire to handle!
   
   I'll try updating to the latest 2.x surefire (2.22.2). If that doesn't change anything I'll try bumping up the Xmx in Travis a bit. Right now it's set to 512m. If _that_ doesn't work then I guess we either need to patch surefire, or refactor the tests to not have so many test cases.
