#1702 [HHQ-2168] bug in DataManager getHistoricalData when specify

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-2168
    public PageList getHistoricalData(List measurements, long begin, long end,


                                      long interval, int type,


                                      boolean returnMetricNulls,


                                      PageControl pc) {

in DataManager when calling this method and specifying returnMetricNulls = false it throws a ConcurrentModificationException

I don't think we are currently using this anywhere in the code with returnMetricNulls = false, but it would be useful
