Re: [eclipselink-users] Sharing of L1 Cache in case of transaction-type="JTA" for persistence unit in persistence.xml 
  An EntityManager represents a unit of work, and so must be isolated until the work is complete and it commits.  What you read might have referred to the L2 cache which is shared, but Caching works the same using JTA as it Resoure_local though.

Best regards,
Chris
