    Description

      Symptom

      When there are the multiple users have a ranking on the same version concurrently, the UI may hang, and the below ConcurrentModificationException is thrown in log file

      java.util.ConcurrentModificationException
at java.util.TreeMap$PrivateEntryIterator.nextEntry(TreeMap.java:1100)
at java.util.TreeMap$KeyIterator.next(TreeMap.java:1154)

...

      Cause

      It seems that in com.pyxis.greenhopper.jira.customfields.RankingCFType TreeMap is used by a static way without synchronized.
      We should fix this problem, and also consider how to handle the concurrent ranking operations by a more friendly method.
