The properties of the returned hash code must be as follows: During the lifetime of a Java application, the hashCode method must return the same integer value every time it is called on a EJBMethodPermission object. The value returned by hashCode for a particular EJBMethodPermission need not remain consistent from one execution of an application to another.
