Gyula Fora created FLINK-4039:
---------------------------------

             Summary: G1 garbage collector only set if no custom jvm arguments
                 Key: FLINK-4039
                 URL: https://issues.apache.org/jira/browse/FLINK-4039
             Project: Flink
          Issue Type: Bug
          Components: Start-Stop Scripts
    Affects Versions: 1.0.0, 1.1.0
            Reporter: Gyula Fora
            Priority: Critical


This can lead to very unexpected behaviour with java 8.

Let's say I want to profile my job so I set some jvm arguments, but this also implicitly change the gc which is kind of weird.
