-------------------------------------------

Yesterday we encountered this issue in a test with local cache and shared=true, the test ran but an NPE exception was noticed in the logs:

>    Affects Versions: 10.0.0.Beta3, 9.4.11.Final
>            Reporter: Ryan Emerson

>
> A shared store does not make sense with a local cache, therefore we should throw a {{CacheConfigurationException}} if configured. Due to assumptions elsewhere in the PersistenceManager, prior to this fix a NPE will be thrown during the Purge method of the store as {{transport == null}}.
