It seems that the current master is broken, with respect to the tests. I see all build on Travis consistently failing, in the gelly project. Since Travis is a bit behind in the "apache" account, I triggered a build in my own account. The hash is the same, it should contain the master from yesterday.
https://travis-ci.org/StephanEwen/incubator-flink/builds/54386416 In all executions it results in the stack trace below. I cannot reproduce the problem locally, unfortunately. This is a serious issue, it totally kills the testability.
