Rick Curtis commented on OPENJPA-1469:
--------------------------------------

Below is the entire list of tests that fail in the openjpa-persistence-jdbc bucket. To recreate
the failures, enable the datacache and re-run. I'm putting this list here because I don't
think I'll be able to get through all of them in the near future.

Failures that have been investigated:
org.apache.openjpa.persistence.spring.TestLibService -- OPENJPA-1767

> I'm proposing that we change the default behavior for the DataCache.  Currently, the
DataCache is turned off by default.  Our competition is turning on their L2 cache by default.
 Thus, out-of-the-box comparisons are killing us.  We have to explain the difference, get
them to change the configuration one way or the other for apples-to-apples comparisons, and
then re-run the benchmark.  By that time, it's too late.  We already lost.
> Due to the upcoming 2.0.0 release, it seems like a good time to change this default.
 Please comment directly to this JIRA.
> Thanks,
> Kevin
