> I'm proposing to move the cacheable class configuration processing from the datacache classes to ClassMetaData. The feature, introduced in OPENJPA-1045, effectively works by returning null for ClassMetaData.getDataCacheName(), where classes which should not be cached return null, otherwise the name of the datacache they may be cached by is returned.
> THe problem is that some third party datacache plugins are not reentrant, and the existing ClassMetaData.isCacheable() makes use of the method call getRepository().getConfiguration().getDataCacheManagerInstance(). This invokes the initialization of the datacache, which may result in further initialization/copying of CMD objects, which reenter the isCacheable() method. If a third party datacache plugin is not reentrant safe, this can cause a failure in the form of Exceptions or hung threads.
