            Description

            Occasionally IcePush throws following exceptions:

            Caused by: java.util.ConcurrentModificationException
                     at java.util.HashMap$HashIterator.nextEntry(HashMap.java:977)
                     at java.util.HashMap$ValueIterator.next(HashMap.java:1006)
                     at java.util.AbstractCollection.toArray(AbstractCollection.java:124)
                     at java.util.ArrayList.<init>(ArrayList.java:131)
                     at org.icepush.servlet.BrowserDispatcher.discardUnusedServlets(BrowserDispatcher.java:89)
                     at org.icepush.servlet.BrowserDispatcher.service(BrowserDispatcher.java:47)
                     at org.icepush.servlet.PathDispatcher.service(PathDispatcher.java:45)
                     at org.icepush.servlet.MainServlet.service(MainServlet.java:71)

            Discarding unused servlets should be thread-safe. This looks to be tightly linked to issue PUSH-151. This exception is thrown from exactly the same line as exception described in issue PUSH-151.

              Synchronization is in place and iteration in both places happens similarly now with new ArrayList being created. Marking this one as FIXED.
