Does Java Connection.close rollback?

Question

Does Java Connection.close rollback into a finally block?.

I know .Net SqlConnection.close does it.

With this I could make try/finally blocks without catch...

Example:

try {
    conn.setAutoCommit(false);
    ResultSet rs = executeQuery(conn, ...);
    ....
    executeNonQuery(conn, ...);
    ....

    conn.commit();
} finally {
   conn.close();
}

According to the javadoc, you should try to either commit or roll back before calling the close method. The results otherwise are implementation-defined.
