The EJB3 container has no way to know what you have in your impl of that method. Unless you explicitly specify as a READ lock, it's by default treated for WRITE lock.

Just mark that timeout method on the singleton to be READ lock type:

import javax.ejb.Lock;
import javax.ejb.LockType;
 
@Lock(LockType.READ)
@Timeout
public void process(javax.ejb.Timer timer) {
...



If you want READ lock to apply to all business methods in that singleton bean, then specify that annotation on the EJB bean class level.
