             Summary: IgniteH2Indexing can throw java.util.ConcurrentModificationException
                 Key: IGNITE-4878
                 URL: https://issues.apache.org/jira/browse/IGNITE-4878
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 1.9
            Reporter: Michael Griggs
            Assignee: Michael Griggs


From the Collections#synchronizedCollection method:

{noformat}
     * It is imperative that the user manually synchronize on the returned
     * collection when traversing it via {@link Iterator}, {@link Spliterator}
     * or {@link Stream}:
     * <pre>
     *  Collection c = Collections.synchronizedCollection(myCollection);
     *     ...
     *  synchronized (c) {
     *      Iterator i = c.iterator(); // Must be in the synchronized block
     *      while (i.hasNext())
     *         foo(i.next());
     *  }
     * </pre>
     * Failure to follow this advice may result in non-deterministic behavior.
