Timer creation is part of the transaction. So if transaction is aborted, the
timer won't be created.
If there is a problem with creating a timer, there should be some kind of an
exception that you get (and logged in the server.log).
You are not allowed to use UserTransaction in an EJB with the container-managed
transaction.
