The Serial filter documentation refers to "process-wide".
It should use the same term used elsewhere within the java runtime to refer to
the runtime scope such as JVM-wide or system-wide.

The term system-wide is used in other places:

    java.security.SecurityPermission
    java.security.Policy
    javax.security.auth.
    javax.security.auth.AuthPermission.java
    conf/security/java.security
    plus various classes in the java.net and java.nio.* packages use system-wide.
