Subject [jira] [Commented] (BEAM-2268) NullPointerException in com.datatorrent.netlet.util.Slice via ApexStateInternals
Date Fri, 12 May 2017 01:23:04 GMT

    [ https://issues.apache.org/jira/browse/BEAM-2268?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16007473#comment-16007473

Thomas Weise commented on BEAM-2268:
------------------------------------

There was an email thread about it a while ago. Please remove the netlet dependency from your
local maven repo and try again.

> I've browsed the code, and this is a certain NPE in netlet 1.2.1 but our dependencies
are on 1.3.0.
> I have read over the dependency tree (both our project and generated archetype) and deliberately
added even tighter deps on 1.3.0. I have not managed to force any dependency on 1.2.1, yet
maven clearly logs its download of 1.2.1 and it appears to be running against it.

> Jenkins obviously has a different configuration, so that is a place to look next, perhaps.
