This originally came up in the context of an older release of the 
proprietary JDK so there has been a bit of prior discussion. We asked 
Sean to bring it here as it applicable to the java.rmi.server.UID that 
is in OpenJDK too. Maybe for 8 or beyond then someone could reexamine 
UID and come up with a way to change the specification that doesn't 
cause compatibility issues.
