Did you ever get an answer to your question or figure out a solution?
I'm faced with a similar situation. Started new Spring MVC web application and I was using Spring 4.2.2 built in ThreadPoolExecutor and Scheduler but realized they did not work under Jboss AS7.
I tried using the org.springframework.jca.work.jboss.JBossWorkManagerTaskExecutor but that didn't work for me either.
Please let me know if you found a solution to the problem somewhere.
