[jira] [Created] (STORM-3315) Upgrade to Kryo 4

Stig Rohde Døssing created STORM-3315:
-----------------------------------------

             Summary: Upgrade to Kryo 4
                 Key: STORM-3315
                 URL: https://issues.apache.org/jira/browse/STORM-3315
             Project: Apache Storm
          Issue Type: Dependency upgrade
    Affects Versions: 2.0.0
            Reporter: Stig Rohde Døssing


A user seems to be hitting https://github.com/EsotericSoftware/kryo/issues/462, which is fixed in Kryo 4.

We should upgrade. It seems like we can ensure compatibility with current Kryo by setting kryo.getFieldSerializerConfig().setOptimizedGenerics(true), going by the Kryo 4 release notes.
