-----------------------------------------
Summary: ConcurrentModificationException when using
$brooklyn:entity
Key: BROOKLYN-352
URL: https://issues.apache.org/jira/browse/BROOKLYN-352
Project: Brooklyn
Issue Type: Bug
Reporter: Svetoslav Neykov
Got the following exception when running a fairly complex blueprint on a cpu

>From Collections.synchronizedMap:
{noformat}
* It is imperative that the user manually synchronize on the returned
* map when iterating over any of its collection views:
