Marshall Schor commented on UIMA-607:
-------------------------------------
Adam points out that the key would need to include the concept of the
application. There is no framework realization of this, other than sharing a
Resource Manager. So the solution would be to have a 3-part key: the resource
manager instance, the class path, and the data path.
