> _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());

> 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.
