Work on OPENJPA-1218 started by Michael Dick.
> Cache.evict(Clazz) should remove subclasses as well
> ---------------------------------------------------

> Key: OPENJPA-1218
> URL: https://issues.apache.org/jira/browse/OPENJPA-1218
> Project: OpenJPA
> Issue Type: Bug
> Components: datacache
> Affects Versions: 2.0.0-M1, 2.0.0-M2, 2.0.0
> Reporter: Kevin Sutter
> Assignee: Michael Dick

> This problem was discovered while working a separate issue with the EHCache
> plugin developer (Craig Andrews). The complete exchange can be found on this
> EHCache bug tracker [1]. According to the latest JPA 2.0 spec, the contract
> for Cache.evict(Clazz) is as follows:
> /**
> * Remove the data for entities of the specified class (and its
> * subclasses) from the cache.
> */
> public void evict(Class cls);
> But, we are not removing the subclasses. We need to change our
> implementation of Cache.evict(Clazz) to be consistent with the spec.
> Also, as we were digging into this area of the code, the internal OpenJPA
> DataCache implementation of the removeAllInternal(Clazz, boolean) method is
> not taking the boolean into account. We should correct this implementation
> at the same time.
> Thanks,
