Subject [jira] [Commented] (FLINK-2826) transformed is modified in BroadcastVariableMaterialization#decrementReferenceInternal without proper locking
Date Sun, 08 Nov 2015 15:33:10 GMT

    [ https://issues.apache.org/jira/browse/FLINK-2826?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14995676#comment-14995676
] 

Stephan Ewen commented on FLINK-2826:
-------------------------------------

I was thinking that if the blocks that synchronize on {{this}} would rather synchronize on
{{references}} as well, it would already solve the issue. What do you think?
