> Currently we use flat mapping for the internal fqn. But this creates problem for concurrent access as every pojo will contend for the root access, e.g., "__JBossInternal__/xxx". End result is there will be lock upgrade exception and needs to be re-tried. The proposed solution is to use additional layer of mapping, e.g.,
> Internal fqn is now structured as:
>  * a) If no region -- /__JBossInternal__/realId/__ID__/xxxx
>  * b) If there is region -- /region/__JBossInternal__/xxx
