WF 29.0.1.Final - JPA - NOT_SUPPORTED - giving IJ031040

[Arnie Morein]

Never seen this before, a DAO method annotated with NOT_SUPPORTED (it just returns a bunch of DTOs for a drop-down list) throws an error inside getResultList()!

IJ031040: Connection is not associated with a managed connection:org.jboss.jca.adapters.jdbc.jdk8.WrappedConnectionJDK8@42932039

The behavior seems to indicate that a connection is opened by the entityManager, the query run, results found, but when JPA calls .next to get the first result, that error is thrown.

If I set it to REQUIRES_NEW (so it doesn't participate in any transaction), it works as expected.

Is this a new bug?

Hey.
Im tad rusty on this front, but AFAIR, NOT_SUPPORTED and according to doc: https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/transaction/annotation/Propagation.html#NOT_SUPPORTED - means that existing transaction is suspended and logic executed outside of it.
REQUIERS_NEW is slightly different, as it starts new transaction after suspending existing one: https://docs.spring.io/spring-framework/docs/current/javadoc-api/org/springframework/transaction/annotation/Propagation.html#REQUIRES_NEW

As to rest dont dare to guess. Could you share simple reproducer and/or config/setup ?

[Arnie Morein]

Well aware of that.

But I am referring to the EJB/JEE version, not Spring.

Could you give us an exception call stack that contains as much of the WildFly code as possible.  Feel free to change your application class + method names if they reveal anything that you don't want to be visible.

I think the call stack will give us a better idea of what is going on. 

An alternative could be enabling (WildFly) TRACE logging for "org.jboss.as.jpa" as mentioned in https://docs.wildfly.org/29/Developer_Guide.html#troubleshooting which I think would also be helpful to share as it should illustrate what is going on better than an exception call stack.
