Thread safety of static variables in EJB

I understand that the spec allows final static variables in EJBs. I have seen code that does this in a stateless session bean:
private final static MyHelperClass HELPER = new MyHelperClass();
This is done so that the same instance of the helper class can be used by all of the EJBs of that type.
This looks like it would not be thread safe unless MyHelperClass had no member variables or synchronized access to its member variables.
What are your thoughts on this?
