Description

This is a subtask for ~~OPENJPA-637~~ to provide a configuration option that allows selection of the cache store implementation used for data caching. Minimally, it should provide a choice between the new java.util.concurrent.ConcurrentHashMap-based implementation and the legacy/1.0.x OpenJPA ConcurrentHashMap. Documentation will be needed to explain the behavioral differences between the options and environments where one option may be a more ideal choice over the other.
