> Key: WFLY-9542
> URL: https://issues.jboss.org/browse/WFLY-9542
> Project: WildFly
> Issue Type: Bug
> Components: EJB
> Affects Versions: 10.1.0.Final
> Reporter: Nuno Godinho de Matos
> Priority: Major
> Labels: Arjuna, IronJacamar, JTA
> Attachments: deploy.log

> I have been trying to understand for what reason we sometimes are seing the exception:
> {panel}
> IJ000311: Throwable from unregister connection: java.lang.IllegalStateException: IJ000152: Trying to return an unknown connection: org.jboss.jca.adapters.jdbc.jdk7.WrappedConnectionJDK7@2021ff6.
> {panel}
> I have now created a sample application that allows the exception to be reproduced:
> https://github.com/99sono/wildlfly-ironjacamar-unregisterconnection/
> To summarize:
> If we start a JTA transaction T1 by invoking an @EJB with TransacitonAttirbute RequiresNew.
> And then this EJB calls a second EJB with TransacitonAttirbute Supports.
> Then we will have the problem that if the First JDBC access is done on the nested EJB, the connection handed over to the JPA layer (eclipselink) will be popped out of the
> org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl.currentObjects
> As soon as we come out of the Nested EJB call.
> I do not know how serious this is.
> If somehow the popped out connection continues in fact locked to the ongoing JTA transaction or if might be going back to the connection pool and potentially be up for grabs.
> This I do not know how... I lack the knowledge to say how crucial it is to have a good synchrinization between the connections being managed under the:
> org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl
> And the JPA layer.
> But intuitively, I would say: quite important.
> So whenever a Stack gets popped with connections being managed, I would intuitively say: one of the parties has done something wrong. Either:
> (a) ARJUNA is asking JAC AMAR to open stacks when the JTA transaction is the same and it shouldn't, or
> (b) It does not really matter that the conneciton is popped out - somehow JAC AMAR still knows that the connection it popped out is still bound to the JTA transaction and the problem is logically strange but of low impact...
> What appears to be true, is that eclipselink is doing something logicla, in the sense that it is only asking for the conneciton to be closed/unregistered at the end of the JTA transaction.
> NOTE:
> In fact the error that we see when we get the stack trace, could also happen and no stack trance be logged by jac AMAR.
> This is the scenario when JAC leaves the unregister conneciton via:
> org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl would be going out via the:
> {panel}
> CopyOnWriteArrayList<ConnectionRecord> conns = cmToConnectionsMap.get(cm);
> // Can happen if connections are "passed" between contexts
> if (conns == null)
> return;
> {panel}
> But in my oppinion this exit path deserves the exact same stack trace.
> The sample application is to be found here:
> https://github.com/99sono/wildlfly-ironjacamar-unregisterconnection/
> This sample application is not as simple to deploy because one needs to hava a data source configured.
> In any case the sample application has in src/test/resources my standalone.xml.
> It should be realtively easy to fix the JDBC drivers configured in the atnadlone.xml.
> And it should be relatively simple to fix the persistence.xml to search for eclipselink in the appropriate moduel.
> I will no copy paste bellow the LOG of the exception of the sample application.

Meanwhile internally, our CachedConnectionManagerImpl, for this thread, has a single task of keys in its currentObjects field
> 4. The leading key on this stack does not hold any connectionrecords (eclipselink returned the connecton to the pool) but it does have a KEY for the JDBC connection manager 5. Point 4 is the magical step to allow us to see the stack trace but not the core of the issue - just the core of seing the stack trace

> 1. We will leave a nested EJB call but not the JTA transaction 2. Wildfly will go to the cachedConnectonManagerImpl and tell it to pop a stack (BUG) 3. The stack that goes away is actually holding the JDBC connection thta has been given to ECLIPSELINK and thta eclipselink will later try to close 4. When we leave this call we go back to STACK 1, where no connections are being managed

> In short we are about to reproduce the stack trace.
> What will now happen is the following.
> 1. Wildfly will tell eclipselink that the transaction is at an end and it should commit if it can
> 2. Eclipselink does its job of committing the changes and takes the JTA connection it was given and tries to close it
> 3. IRON JAC AMAR will log the stack trace we wanted to reproduce saying it has not idea what connection we are trying to return to the pool.
> 4. The reason the CachedConnectionManagerImpl does not know about the connection is because it was managed under STACK 2 but was popped out of existence after the nested transaction
> 5. Now it is very important to keep in mind that even if we were not seing the stack trace the error would be there (the moment we popped a key stack that had still connections) 6. Keep in mind that if we were to modify the source code and disable our reproduceBugService.fetchAlIds() call we would see no stack trace but the same issue would be present.7. The difference that doing the reproduceBugService.fetchAlIds() does is whether or not CachedConnectionManagerImpl during unregister connection leaves via the if conns == null return null or if goes further into the if (!ignoreConnections)
> 8. OK - Now that we understand what is happening behind the scenes we can let eclipselink try to close the JDBC connection at the end of the JTA transaction

> IJ000311: Throwable from unregister connection: java.lang.IllegalStateException: IJ000152: Trying to return an unknown connection: org.jboss.jca.adapters.jdbc.jdk7.WrappedConnectionJDK7@2021ff6.
> {panel}
> I have now created a sample application that allows the exception to be reproduced:
> https://github.com/99sono/wildlfly-ironjacamar-unregisterconnection/
> To summarize:
> If we start a JTA transaction T1 by invoking an @EJB with TransacitonAttirbute RequiresNew.
> And then this EJB calls a second EJB with TransacitonAttirbute Supports.
> Then we will have the problem that if the First JDBC access is done on the nested EJB, the connection handed over to the JPA layer (eclipselink) will be popped out of the
> org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl.currentObjects
> As soon as we come out of the Nested EJB call.
> I do not know how serious this is.
> If somehow the popped out connection continues in fact locked to the ongoing JTA transaction or if might be going back to the connection pool and potentially be up for grabs.
> This I do not know how... I lack the knowledge to say how crucial it is to have a good synchrinization between the connections being managed under the:
> org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl
> And the JPA layer.
> But intuitively, I would say: quite important.
> So whenever a Stack gets popped with connections being managed, I would intuitively say: one of the parties has done something wrong. Either:
> (a) ARJUNA is asking JAC AMAR to open stacks when the JTA transaction is the same and it shouldn't, or
> (b) It does not really matter that the conneciton is popped out - somehow JAC AMAR still knows that the connection it popped out is still bound to the JTA transaction and the problem is logically strange but of low impact...
> What appears to be true, is that eclipselink is doing something logicla, in the sense that it is only asking for the conneciton to be closed/unregistered at the end of the JTA transaction.
> NOTE:
> In fact the error that we see when we get the stack trace, could also happen and no stack trance be logged by jac AMAR.
> This is the scenario when JAC leaves the unregister conneciton via:
> org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl would be going out via the:
> {panel}
> CopyOnWriteArrayList<ConnectionRecord> conns = cmToConnectionsMap.get(cm);
> // Can happen if connections are "passed" between contexts
> if (conns == null)
> return;
> {panel}
> But in my oppinion this exit path deserves the exact same stack trace.
> The sample application is to be found here:
> https://github.com/99sono/wildlfly-ironjacamar-unregisterconnection/
> This sample application is not as simple to deploy because one needs to hava a data source configured.
> In any case the sample application has in src/test/resources my standalone.xml.
> It should be realtively easy to fix the JDBC drivers configured in the atnadlone.xml.
> And it should be relatively simple to fix the persistence.xml to search for eclipselink in the appropriate moduel.
> I will no copy paste bellow the LOG of the exception of the sample application.

> 4. The leading key on this stack does not hold any connectionrecords (eclipselink returned the connecton to the pool) but it does have a KEY for the JDBC connection manager 5.

> 1. We will leave a nested EJB call but not the JTA transaction 2. Wildfly will go to the cachedConnectonManagerImpl and tell it to pop a stack (BUG) 3. The stack that goes away is actually holding the JDBC connection thta has been given to ECLIPSELINK and thta eclipselink will later try to close 4.

> In short we are about to reproduce the stack trace.
> What will now happen is the following.
> 1. Wildfly will tell eclipselink that the transaction is at an end and it should commit if it can
> 2. Eclipselink does its job of committing the changes and takes the JTA connection it was given and tries to close it
> 3. IRON JAC AMAR will log the stack trace we wanted to reproduce saying it has not idea what connection we are trying to return to the pool.
> 4. The reason the CachedConnectionManagerImpl does not know about the connection is because it was managed under STACK 2 but was popped out of existence after the nested transaction
> 5. Now it is very important to keep in mind that even if we were not seing the stack trace the error would be there (the moment we popped a key stack that had still connections) 6. Keep in mind that if we were to modify the source code and disable our reproduceBugService.fetchAlIds() call we would see no stack trace but the same issue would be present.7. The difference that doing the reproduceBugService.fetchAlIds() does is whether or not CachedConnectionManagerImpl during unregister connection leaves via the if conns == null return null or if goes further into the if (!ignoreConnections)
> 8. OK - Now that we understand what is happening behind the scenes we can let eclipselink try to close the JDBC connection at the end of the JTA transaction

> Thanks for considering this issue.
> I do not know how much impact this issue can actually have.
> We have many hundred different types of JTA business transactions, and we see this sample application happening on system tests and stress tests relatively often.
> Now that I have better understand of the issue, I can in some cases rework the code to dodge this problem to avoid nested calls of EJBS on the same transaciton - but this will not always be possible.
> And I would be quite afraid of this issue, if means that our connectons still in the hands of ElcipseLInk are going back to the pool.
> This would explain some strange errors we have had only on stress test application, that we do not see when using a different app server.
> I must say it was extremelly difficult to be able to make the stack trace reproducible.
> There are many tricky points to be able to lead the code to go precisely through the code path that leads to the excpetion.
> But it is relatively trivial to make the code leave through the "silent bug iron jac amar code path".
> Many thanks for all the help on this.
