Kenneth Knowles commented on BEAM-3492:
---------------------------------------
This is quite common:
https://builds.apache.org/job/beam_PreCommit_Java_MavenInstall/org.apache.beam$beam-examples-java/16902/console
I notice that it does not happen in the gradle build. Perhaps it has to do with
the one maven profile that includes all the runners. Since the maven config is
known bad, we could just transition this particular signal completely to gradle
and the problem is already fixed.
