Brian Ghigiarelli commented on STORM-120:
-----------------------------------------
Any progress on this bug? With parallel streams for Collections in Java 8, this
issue seems like it should bump up in priority.
> util/acquire-random-range-id is not thread-safe

> Key: STORM-120
> URL: https://issues.apache.org/jira/browse/STORM-120
> Project: Apache Storm
> Issue Type: Bug
> Reporter: James Xu
> Priority: Minor

> https://github.com/nathanmarz/storm/issues/724
> Concurrent calls to util/acquire-random-range-id with the same parameters can
> result in an IndexOutOfBoundsException, as an increment in one thread may
> occur after the bounds check in another. The resulting curr value can be >=
> the size of the List state.
