Subject [jira] [Commented] (DRILL-2219) Concurrent modification exception in TopLevelAllocator if a child allocator is added during loop in close()
Date Thu, 26 Feb 2015 19:41:05 GMT

    [ https://issues.apache.org/jira/browse/DRILL-2219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14338998#comment-14338998

Jason Altekruse commented on DRILL-2219:
----------------------------------------

This actually doesn't work, Collections.synchronizedMap() does not protect the iterators used
in extended for loops.
