[ https://issues.redhat.com/browse/JBTM-3088?page=com.atlassian.jira.plugin... ] Ondrej Chaloupka commented on JBTM-3088: ---------------------------------------- My trouble happens when the recovery runs on the Remote EJB XAResource and authentication is wrongly setup. In such case the call to `recover` throws an exception. https://github.com/jbosstm/narayana/blob/5.10.4.Final/ArjunaJTA/jta/class... On the follow-up call during the second pass of recovery the `NPE` may be obtained https://github.com/jbosstm/narayana/blob/5.10.4.Final/ArjunaJTA/jta/class... The stacktrace of the exception I work with is {code} WARN [com.arjuna.ats.jta] (Periodic Recovery) ARJUNA016027: Local XARecoveryModule.xaRecovery got XA exception XAException.XAER_RMFAIL: javax.transaction.xa.XAException: WFTXN0034: Failed to acquire a connection for this operation at org.wildfly.transaction.client@1.1.7.Final//org.wildfly.transaction.client.provider.remoting.RemotingRemoteTransactionPeer.getPeerIdentityXA(RemotingRemoteTransactionPeer.java:96) at org.wildfly.transaction.client@1.1.7.Final//org.wildfly.transaction.client.provider.remoting.RemotingRemoteTransactionPeer.recover(RemotingRemoteTransactionPeer.java:203) at org.wildfly.transaction.client@1.1.7.Final//org.wildfly.transaction.client.SubordinateXAResource.recover(SubordinateXAResource.java:210) at org.wildfly.transaction.client@1.1.7.Final//org.wildfly.transaction.client.SubordinateXAResource.recover(SubordinateXAResource.java:206) at org.jboss.jts//com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule.xaRecoveryFirstPass(XARecoveryModule.java:634) at org.jboss.jts//com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule.periodicWorkFirstPass(XARecoveryModule.java:226) at org.jboss.jts//com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule.periodicWorkFirstPass(XARecoveryModule.java:171) at org.jboss.jts//com.arjuna.ats.internal.arjuna.recovery.PeriodicRecovery.doWorkInternal(PeriodicRecovery.java:770) at org.jboss.jts//com.arjuna.ats.internal.arjuna.recovery.PeriodicRecovery.run(PeriodicRecovery.java:382) Caused by: org.wildfly.security.auth.AuthenticationException: JBREM000308: Authentication failed (no mechanisms left), tried: JBOSS-LOCAL-USER: org.wildfly.security.auth.AuthenticationException: JBREM000300: Authentication failed due to I/O error at org.jboss.remoting@5.0.15.Final//org.jboss.remoting3.ConnectionPeerIdentityContext.doAuthenticate(ConnectionPeerIdentityContext.java:379) at org.jboss.remoting@5.0.15.Final//org.jboss.remoting3.ConnectionPeerIdentityContext.authenticate(ConnectionPeerIdentityContext.java:183) at org.jboss.remoting@5.0.15.Final//org.jboss.remoting3.EndpointImpl$3.lambda$handleDone$0(EndpointImpl.java:529) at org.jboss.threads@2.3.3.Final//org.jboss.threads.ContextClassLoaderSavingRunnable.run(ContextClassLoaderSavingRunnable.java:35) at org.jboss.threads@2.3.3.Final//org.jboss.threads.EnhancedQueueExecutor.safeRun(EnhancedQueueExecutor.java:1982) at org.jboss.threads@2.3.3.Final//org.jboss.threads.EnhancedQueueExecutor$ThreadBody.doRunTask(EnhancedQueueExecutor.java:1486) at org.jboss.threads@2.3.3.Final//org.jboss.threads.EnhancedQueueExecutor$ThreadBody.run(EnhancedQueueExecutor.java:1377) at java.base/java.lang.Thread.run(Thread.java:834) WARN [com.arjuna.ats.jta] (Periodic Recovery) ARJUNA016009: Caught:: java.lang.NullPointerException at org.jboss.jts//com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule.xaRecoverySecondPass(XARecoveryModule.java:738) at org.jboss.jts//com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule.bottomUpRecovery(XARecoveryModule.java:519) at org.jboss.jts//com.arjuna.ats.internal.jta.recovery.arjunacore.XARecoveryModule.periodicWorkSecondPass(XARecoveryModule.java:270) at org.jboss.jts//com.arjuna.ats.internal.arjuna.recovery.PeriodicRecovery.doWorkInternal(PeriodicRecovery.java:816) at org.jboss.jts//com.arjuna.ats.internal.arjuna.recovery.PeriodicRecovery.run(PeriodicRecovery.java:382) {code} -- This message was sent by Atlassian Jira (v7.13.8#713008)
