Github user zentol commented on the issue: https://github.com/apache/flink/pull/3736 Sorry, I'm rather busy at the moment myself due to the feature freeze and may not be able to try this out in time. To be honest, given that if we merge it for 1.4-SNAPSHOT the jar can be easily ported to 1.3 (just replace the versions in the pom.xml and rebuild it) I'm prioritizing this less than other changes that don't have this luxury.
