Description

BDB JE permits the same environment path to be opened many times from within a single JVM process. The second environment basically becomes a handle for the first.

This use case does not fit with the Java Broker's model which expects stores underlying each virtual host (VH) or virtual host node (VHN) to be independent.

This change will introduce a simple registry which will serve to prevent the same JE store being attached to more than one VH or VHN.
