 * @param id The TransactionUID to commit
 * @param xid The Xid of the transaction to commit. Required if transaction is an XA transaction. Must be null if it is
 * not an XA transaction.
 * @param xaFlags xaFlags passed on COMMIT operation. Used only if an XA transaction.
 * @param ts Current TransactionState of this transaction.
 * @param conlist List of transactions on this connection. Will be null if commit is trigger by an admin request.
 * @param sendReply True to have method send a Status.OK reply while processing transaction. This should be "true" for
 * client initiated commits, "false" for admin initiated commits.
 * @param con Connection client commit packet came in on or, for admin, the connection the admin request came in on.
 * @param msg Client commit packet. Should be "null" for admin initiated commits.

 * @throws BrokerException on an error. The method will have logged a message to the broker log.
