William Burns commented on ISPN-4512:
-------------------------------------

Getting a heap dump when the error occurs I can see multiple GlobalMarshallers referencing the same VersionAwareMarshaller, so it appears it got shared between caches and the shutdown of the one caused an issue with it not initializing in the other.

> When a new cache manager is started with the same configuration, it uses the JGroupsTransport instance. In some rare cases, the JGroupsTransport keeps using the old marshaller, which doesn't work, and the cache fails to start:
