A DESCRIPTION OF THE PROBLEM :
If a java.net.URI is constructed with an URI whose host name
starts with a digit and is not a valid IP address,
java.net.URI.getHost() == null.

This bug is critical in my organization, where the host
names start with the room number. We're deploying RMI
services, and the clients (applets) can't connect with the
registry service because java.rmi.Naming uses java.net.URI
internally. When java.net.URI.getHost() returns null,
java.rmi.Naming tries to connect with a registry in the
local host, producing an AccessControlException (and a
ConnectException).


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. Construct a new java.net.URI with a string representing a
URI in the form :

[scheme]://[one_or_more_digits][remaining_host_name]/[anything]
(for example: rmi://126g/MyServer)

2. java.net.URI.getHost() returns null
(it should return "126g" in that case)


EXPECTED VERSUS ACTUAL BEHAVIOR :
Expected Result:
java.net.URI.getHost() returns the host name

Actual Result:
java.net.URI.getHost() returns null

ERROR MESSAGES/STACK TRACES THAT OCCUR :
No exceptions.

REPRODUCIBILITY :
This bug can be reproduced always.
