With Sybase EAServer, the stubs for EJBHome and EJBObject are thread safe.
It should be noted, however, that trying to access stateful objects from
multiple threads simultaneously can cause problems. For example, two
client threads that use UserTransaction might attempt to access the same
stateful session bean instance within separate transactions (at the same
time). This could result in an INVALID_TRANSACTION system exception for
one of the threads.
