[jboss-jira] [JBoss JIRA] (WFLY-3853) Cache PersistenceProviders within the same deployment

Cache PersistenceProviders within the same deployment ----------------------------------------------------- Key: WFLY-3853 URL: https://issues.jboss.org/browse/WFLY-3853 Project: WildFly Issue Type: Feature Request Components: JPA / Hibernate Reporter: Scott Marlow Assignee: Scott Marlow See wildfly-dev ml discussion [http://lists.jboss.org/pipermail/wildfly-dev/2014-September/002984.html] about calls to PersistenceProviderResolver.getPersistenceProviders() should return a cached list. The cache should be per deployment. We can probably reuse our PersistenceProviderResolverImpl.persistenceProviderPerClassLoader map, just need to be careful that addDeploymentSpecificPersistenceProvider() is called early before any calls to getPersistenceProviders().
