Hi David, Is it possible to fix this on the TSR implementation side?
Specifically, since TSR implementation is registered with JNDI, could you refactor it into a permanent singleton registered in JNDI that delegates to the real implementation?
And the server code notify it the JNDI instance when there is a server state change that would invalidate the implementation. Then the JNDI object could delegate to the new implementation object.
Seems like the only difference between what you're proposing and what I'm proposing is the receiver of the change notification.

Seems there are some slight differences in the way OpenJPA tracks the TransactionManager reference versus the TransactionSynchronizationRegistry. The TransactionManager appears to be fetched once per EntityManagerFactory, so if the underlying app server does any sort of rebooting the new TransactionManager instance is picked up just fine as OpenJPA continues to get it from the app server. This is good. However when it comes to the TransactionSynchronizationRegistry, it seems OpenJPA grabs it once for the life of the VM and never lets it go. So if any sort of rebooting happens in the app server OpenJPA will not get the new TransactionSynchronizationRegistry and of course ceases to work properly.Is it possible we can get this fixed for the next release? -David(pulled these stack traces of the code referencing the old TransactionSynchronizationRegistry, may or may not be useful to you)at org.apache.openjpa.ee.RegistryManagedRuntime $ TransactionManagerRegistryFacade .getStatus(RegistryManagedRuntime.java:130) at org .apache .openjpa .kernel .AbstractBrokerFactory .syncWithManagedTransaction(AbstractBrokerFactory.java:723) at org.apache.openjpa.kernel.BrokerImpl.initialize(BrokerImpl.java: 320) at org .apache .openjpa .kernel .AbstractBrokerFactory.initializeBroker(AbstractBrokerFactory.java: 216) at org .apache .openjpa .kernel.AbstractBrokerFactory.newBroker(AbstractBrokerFactory.java: 190) at org .apache .openjpa .kernel .DelegatingBrokerFactory.newBroker(DelegatingBrokerFactory.java:142) at org .apache .openjpa .persistence .EntityManagerFactoryImpl .createEntityManager(EntityManagerFactoryImpl.java:192) at org .apache .openjpa .persistence .EntityManagerFactoryImpl .createEntityManager(EntityManagerFactoryImpl.java:56)--at org.apache.openjpa.ee.RegistryManagedRuntime $ TransactionManagerRegistryFacade .getStatus(RegistryManagedRuntime.java:130) at org .apache .openjpa .kernel .AbstractBrokerFactory .syncWithManagedTransaction(AbstractBrokerFactory.java:723) at org .apache .openjpa .kernel.BrokerImpl.syncWithManagedTransaction(BrokerImpl.java:1391) at org .apache .openjpa .kernel .DelegatingBroker.syncWithManagedTransaction(DelegatingBroker.java: 893) at org .apache .openjpa .persistence .EntityManagerImpl.joinTransaction(EntityManagerImpl.java:501)--at org.apache.openjpa.ee.RegistryManagedRuntime $ TransactionManagerRegistryFacade .registerSynchronization(RegistryManagedRuntime.java:118) at org .apache .openjpa .kernel .AbstractBrokerFactory .syncWithManagedTransaction(AbstractBrokerFactory.java:735) at org .apache .openjpa .kernel.BrokerImpl.syncWithManagedTransaction(BrokerImpl.java:1391) at org .apache .openjpa .kernel .DelegatingBroker.syncWithManagedTransaction(DelegatingBroker.java: 893) at org .apache .openjpa .persistence .EntityManagerImpl.joinTransaction(EntityManagerImpl.java:501)--at org.apache.openjpa.ee.RegistryManagedRuntime $ TransactionManagerRegistryFacade .getTransactionKey(RegistryManagedRuntime.java:134) at org .apache .openjpa .ee .RegistryManagedRuntime .getTransactionKey(RegistryManagedRuntime.java:88) at org .apache .openjpa .ee .AutomaticManagedRuntime .getTransactionKey(AutomaticManagedRuntime.java:255) at org .apache .openjpa .kernel .AbstractBrokerFactory .syncWithManagedTransaction(AbstractBrokerFactory.java:740) at org .apache .openjpa .kernel.BrokerImpl.syncWithManagedTransaction(BrokerImpl.java:1391) at org .apache .openjpa .kernel .DelegatingBroker.syncWithManagedTransaction(DelegatingBroker.java: 893) at org .apache .openjpa .persistence .EntityManagerImpl.joinTransaction(EntityManagerImpl.java:501)--at org.apache.openjpa.ee.RegistryManagedRuntime $ TransactionManagerRegistryFacade .registerSynchronization(RegistryManagedRuntime.java:118) at org .apache .openjpa .kernel .AbstractBrokerFactory .syncWithManagedTransaction(AbstractBrokerFactory.java:746) at org .apache .openjpa .kernel.BrokerImpl.syncWithManagedTransaction(BrokerImpl.java:1391) at org .apache .openjpa .kernel .DelegatingBroker.syncWithManagedTransaction(DelegatingBroker.java: 893) at org .apache .openjpa .persistence .EntityManagerImpl.joinTransaction(EntityManagerImpl.java:501)
