User transaction timeout not working

As we transition to the new Hyland Community, some post links may be temporarily disrupted as we finalize redirects. We apologize for the inconvenience and are working to resolve this as quickly as possible. Details.

I have a user transaction set up similar to this:

        UserTransaction transaction = getTransactionService().getNonPropagatingUserTransaction();
        try {
            transaction.setTransactionTimeout(60);
            transaction.begin();
            long start = System.currentTimeMillis();
            Object responseObj = executeWS(request, response);
            if (responseObj != null) {
                writeResponseObjectToResponse(request, response, responseObj);
            }else {
                response.getWriter().write("");
            }
            long end = System.currentTimeMillis();
            transaction.commit();
            if (LOGGER.isInfoEnabled()) {
                double time = (end - start) / 1000.0;
                LOGGER.info(String.format("Transaction complete after %.2f seconds.", time));
            }
        } catch(Exception e) {
            try {
                transaction.rollback();
            } catch (SystemException se) {
                throw new WebScriptException("Error during rollback.", se);
            }
            throw new WebScriptException("Error executing Web Script " + getDescription() + ".", e);
        }

The transaction does not timeout before the 60 second limit. Is timeout enabled in Alfresco's implementation? Is there something else I could use to timeout and rollback the transaction?

I realize that timing out a running transaction is not an ideal solution but it is what I'v been ordered to do.

The UserTransaction object returned bye TransactionService.getNonPropagatingUserTransaction() method is  an instance of org.alfresco.service.transaction.SpringAwareUserTransaction

It seems although SpringAwareUserTransaction implemented the required method setTransactionTimeout,it dose not at all use the time out settings and dose not at all handle time out.
