[cdi-dev] [JBoss JIRA] (CDI-523) CDI spec tries to dispose a container-managed entity manager.

[ https://issues.jboss.org/browse/CDI-523?page=com.atlassian.jira.plugin.sy... ] Martin Andersson updated CDI-523: --------------------------------- Description: Section "3.5.2. Declaring a disposer method" has this example: {code:java} public class Resources { @PersistenceContext @Produces @UserDatabase private EntityManager em; public void close(@Disposes @UserDatabase EntityManager em) { em.close(); } } {code} The disposer method above call {{EntityManager.close()}} on a container-managed entity manager which result in an {{IllegalStateException}} being thrown *and* the entity manager remains open. This behavior is expected as the JPA specification forbids application code to close a container-managed entity manager. JPA 2.1, section "7.9.1 Container Responsibilities" says: {quote} The container must throw the IllegalStateException if the application calls EntityManager.close on a container-managed entity manager. {quote} This has been proved [here|https://github.com/MartinanderssonDotcom/java-ee-concepts/blob/maste...] and a theoretical walkthough surrounding entity managers combined with CDI scopes is available [here|https://github.com/MartinanderssonDotcom/java-ee-concepts/blob/maste...]. was: Section "3.5.2.
