Subject [jira] [Commented] (BEAM-630) DataflowRunnableOnService test suite is broken
Date Tue, 13 Sep 2016 20:56:21 GMT

    [ https://issues.apache.org/jira/browse/BEAM-630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15488397#comment-15488397
] 

Eugene Kirpichov commented on BEAM-630:
---------------------------------------

Wonderful. This seems like a bug in ByteBuddy - it legitimately produces a broken class file,
but in some cases JVM skips verifying it. With -DforkCount=0 it doesn't, for some reason I
don't quite understand yet (and it probably doesn't matter), but with -XX:+BytecodeVerificationLocal
it fails even when run as a test method from IDEA.

Don't ask how I found out (hint: I found out by reading JVM source code).
