Exposure to run JVM under root?

We noticed that a JMS application running on a WebSphere application Server (not inside the J2EE container) is trying to access some resources using the UserId root. We checked with the developers, they said they did not specify any userId and it may be WAS is assigning the userId running the JVM to the JMS application. They said that the JVM is started with root userId. Does this sounfd like an security exposure? If the JMS application is running as root, does it mean that they can add code to the program to do something else they needs root authority ? Should we stop them from starting a JVM under root ?

Make a user for your WAS.
It's good practice and highly manageable, also secure.
Consult your documentation how to setup, it should also be user based, and not root.

You can run it, it will work, but i would advise against it, since it can cause various problems (exploit code running under root user can actually do alot of damage, NFS 'issues' etc.)
