[jira] [Created] (FLINK-930) Netty Initialization is sometimes very slow

Stephan Ewen created FLINK-930:
----------------------------------

             Summary: Netty Initialization is sometimes very slow
                 Key: FLINK-930
                 URL: https://issues.apache.org/jira/browse/FLINK-930
             Project: Flink
          Issue Type: Bug
            Reporter: Stephan Ewen


I often see the initialization of Netty taking 3 seconds and then failing with the message 

"WARN  io.netty.util.internal.ThreadLocalRandom                      - Failed to generate a seed from SecureRandom within 3 seconds. Not enough entrophy?"

This adds to every single run a 3 seconds delay, which is often more than the test time and causes our builds to run out of time.
