Need to add checkTransaction handling for unwrap connection ----------------------------------------------------------- Key: JBJCA-1392 URL: https://issues.jboss.org/browse/JBJCA-1392 Project: IronJacamar Issue Type: Bug Components: JDBC Reporter: Ivo Studensky Assignee: Ivo Studensky Priority: Major Labels: downstream_dependency _connection.setAutoCommit_ cannot affect _unwrap_ native connection. The following _mc.getAutoCommit_ result is true. {code} c = dataSource.getConnection(); c.setAutoCommit(false); if (c.isWrapperFor(oracle.jdbc.OracleConnection.class)) { mc = c.unwrap(oracle.jdbc.OracleConnection.class); } System.out.println("[JDBC 4 Wrapper] autoCommit : " + mc.getAutoCommit()); {code} However, the following _getUnderlyingConnection_ native connection result is false. {code} c = dataSource.getConnection(); c.setAutoCommit(false); WrappedConnection wc = (WrappedConnection)c; oracle.jdbc.OracleConnection mc = (oracle.jdbc.OracleConnection)wc.getUnderlyingConnection(); System.out.println("[org.jboss.ironjacamar.jdbcadapters WrappedConnection] autoCommit : " + mc.getAutoCommit()); {code} The _getUnderlyingConnection_ method call _BaseWrapperManagedConnection.checkTransaction_ process, but there is no similar process in _unwrap_ method. {code:title=org/jboss/jca/adapters/jdbc/BaseWrapperManagedConnection.java|borderStyle=solid} void checkTransaction() throws SQLException { synchronized (stateLock) { if (inManagedTransaction) return; // Check autocommit if (jdbcAutoCommit != underlyingAutoCommit) { con.setAutoCommit(jdbcAutoCommit); underlyingAutoCommit = jdbcAutoCommit; } } {code}
