Description

There are race conditions in the retrieval of immediately invalidate resources from the SharedResourcesBroker. This can result in an object being returned multiple times even though it should only be returned once. It can also result in valid objects being invalidated before a thread picks it up and it can also result in stack overflow due to a thread starving and retrying many times.
