      connection.setAutoCommit cannot affect unwrap native connection. The following mc.getAutoCommit result is true.

      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());

      However, the following getUnderlyingConnection native connection result is false.

      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());

      The getUnderlyingConnection method call BaseWrapperManagedConnection.checkTransaction process, but there is no similar process in unwrap method.

      org/jboss/jca/adapters/jdbc/BaseWrapperManagedConnection.java
         void checkTransaction() throws SQLException
   {
      synchronized (stateLock)
      {
         if (inManagedTransaction)
            return;

         // Check autocommit
         if (jdbcAutoCommit != underlyingAutoCommit)
         {
            con.setAutoCommit(jdbcAutoCommit);
            underlyingAutoCommit = jdbcAutoCommit;
         }
      }
