SQLException.getSQLState() and getCause() are null with XADatasource connection for postgresql during network failure --------------------------------------------------------------------------------------------------------------------- Key: JBJCA-1391 URL: https://issues.jboss.org/browse/JBJCA-1391 Project: IronJacamar Issue Type: Bug Components: JDBC Reporter: Ivo Studensky Assignee: Ivo Studensky Priority: Major When using staled connection of xa datasource, the connection throws SQLException. Then SQLException.getSQLState() and getCause() returns null if using XA datasource. The SQLException is re-created in the following stack. {code} #####: java.sql.SQLException: Error at org.jboss.jca.adapters.jdbc.WrappedConnection.checkException(WrappedConnection.java:2033) at org.jboss.jca.adapters.jdbc.WrappedStatement.checkException(WrappedStatement.java:1436) at org.jboss.jca.adapters.jdbc.WrappedPreparedStatement.executeQuery(WrappedPreparedStatement.java:509) at com.example.SelectXaServlet.doGet(SelectXaServlet.java:41) {code} - adapters/src/main/java/org/jboss/jca/adapters/jdbc/WrappedConnection.java {code} protected SQLException checkException(Throwable t) throws SQLException { Throwable result = null; if (t instanceof AbstractMethodError) { t = new SQLFeatureNotSupportedException(bundle.methodNotImplemented(), t); } if (mc != null) result = mc.connectionError(t); if (result instanceof SQLException) { throw (SQLException) result; } else { throw new SQLException("Error", result); // If the managed connection is null, create a new SQLException. } } {code} In the above, the managed connection is null. This is because that the ConnectionEventListener#connectionErrorOccurred() fired by the Postgresql driver. (oracle driver doesn't fire the event during executing statement, so this issue doen't occur.) {code} at org.jboss.jca.adapters.jdbc.WrappedConnection.setManagedConnection(WrappedConnection.java:120) // null set at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.cleanup(BaseWrapperManagedConnection.java:339) - locked <0x00000000f9ea3560> (a java.util.HashSet) at org.jboss.jca.core.connectionmanager.pool.mcp.SemaphoreConcurrentLinkedDequeManagedConnectionPool.returnConnection(SemaphoreConcurrentLinkedDequeManagedConnectionPool.java:666) at org.jboss.jca.core.connectionmanager.pool.mcp.SemaphoreConcurrentLinkedDequeManagedConnectionPool.returnConnection(SemaphoreConcurrentLinkedDequeManagedConnectionPool.java:611) at org.jboss.jca.core.connectionmanager.pool.AbstractPool.returnConnection(AbstractPool.java:847) at org.jboss.jca.core.connectionmanager.AbstractConnectionManager.returnManagedConnection(AbstractConnectionManager.java:725) at org.jboss.jca.core.connectionmanager.listener.AbstractConnectionListener.connectionErrorOccurred(AbstractConnectionListener.java:472) at org.jboss.jca.adapters.jdbc.BaseWrapperManagedConnection.broadcastConnectionError(BaseWrapperManagedConnection.java:673) at org.jboss.jca.adapters.jdbc.xa.XAManagedConnection.broadcastConnectionError(XAManagedConnection.java:203) at org.jboss.jca.adapters.jdbc.xa.XAManagedConnection$1.connectionErrorOccurred(XAManagedConnection.java:91) at org.postgresql.ds.PGPooledConnection.fireConnectionFatalError(PGPooledConnection.java:183) at org.postgresql.ds.PGPooledConnection.fireConnectionError(PGPooledConnection.java:237) at org.postgresql.ds.PGPooledConnection.access$200(PGPooledConnection.java:38) at org.postgresql.ds.PGPooledConnection$StatementHandler.invoke(PGPooledConnection.java:428) at com.sun.proxy.$Proxy64.executeQuery(Unknown Source) at org.jboss.jca.adapters.jdbc.WrappedPreparedStatement.executeQuery(WrappedPreparedStatement.java:504) at com.example.SelectXaServlet.doGet(SelectXaServlet.java:41) {code} adapters/src/main/java/org/jboss/jca/adapters/jdbc/xa/XAManagedConnection.java {code} public XAManagedConnection(XAManagedConnectionFactory mcf, XAConnection xaConnection, Properties props, int transactionIsolation, int psCacheSize) throws SQLException { super(mcf, xaConnection.getConnection(), props, transactionIsolation, psCacheSize); this.xaConnection = xaConnection; xaConnection.addConnectionEventListener(new javax.sql.ConnectionEventListener() { ...<snip> public void connectionErrorOccurred(javax.sql.ConnectionEvent ce) { SQLException ex = ce.getSQLException(); broadcastConnectionError(ex); // cleanup and return this connection when this event fired. } }); {code}
