[ https://issues.jboss.org/browse/TEIID-3435?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-3435: ---------------------------------- Summary: IllegalStateException closing connection (was: XML subquery plans being closed twice) Description: Another thing from the log are what appear to be exceptions related to close calls: {code} 10:30:27,074 INFO [org.jboss.jca.core.connectionmanager.listener.TxConnectionListener] (http-localhost/127.0.0.1:8080-1) IJ000311: Throwable from unregister connection: java.lang.IllegalStateException: Trying to return an unknown connection2! org.jboss.jca.adapters.jdbc.jdk6.WrappedConnectionJDK6@b036577 at org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl.unregisterConnection(CachedConnectionManagerImpl.java:347) at org.jboss.jca.core.connectionmanager.listener.TxConnectionListener.connectionClosed(TxConnectionListener.java:371) at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.closeHandle(BaseWrapperManagedConnection.java:574) at org.jboss.jca.adapters.jdbc.WrappedConnection.close(WrappedConnection.java:265) at org.teiid.translator.jdbc.JDBCExecutionFactory.closeConnection(JDBCExecutionFactory.java:287) at org.teiid.translator.jdbc.JDBCExecutionFactory.closeConnection(JDBCExecutionFactory.java:51) at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.close(ConnectorWorkItem.java:226) [teiid-engine-8.4.2-redhat-1.jar:8.4.2-redhat-1] {code} It looks like it's only happening for the XML subplans. We explicitly prevent close from being called multiple times on connector work item. was: Another thing from the log are what appear to be exceptions related to double close calls: {code} 10:30:27,074 INFO [org.jboss.jca.core.connectionmanager.listener.TxConnectionListener] (http-localhost/127.0.0.1:8080-1) IJ000311: Throwable from unregister connection: java.lang.IllegalStateException: Trying to return an unknown connection2! org.jboss.jca.adapters.jdbc.jdk6.WrappedConnectionJDK6@b036577 at org.jboss.jca.core.connectionmanager.ccm.CachedConnectionManagerImpl.unregisterConnection(CachedConnectionManagerImpl.java:347) at org.jboss.jca.core.connectionmanager.listener.TxConnectionListener.connectionClosed(TxConnectionListener.java:371) at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.closeHandle(BaseWrapperManagedConnection.java:574) at org.jboss.jca.adapters.jdbc.WrappedConnection.close(WrappedConnection.java:265) at org.teiid.translator.jdbc.JDBCExecutionFactory.closeConnection(JDBCExecutionFactory.java:287) at org.teiid.translator.jdbc.JDBCExecutionFactory.closeConnection(JDBCExecutionFactory.java:51) at org.teiid.dqp.internal.datamgr.ConnectorWorkItem.close(ConnectorWorkItem.java:226) [teiid-engine-8.4.2-redhat-1.jar:8.4.2-redhat-1] {code} It looks like it's only happening for the XML subplans. But it seems odd as we explicitly prevent close from being called multiple times on connector work item. Changed the issue text as it does not appear to be about double closing.
