<i18n dev> TimeZone.DispayNames - remove it?

[Alan Bateman]

While snooping around in java.util.TimeZone I came across DisplayNames 
which doesn't appear to be be used anymore as the display cache is moved 
to TimeZoneNameUtility. Any objection if I remove it via the attached 
patched? The JDK builds without it and I am confident it is not used 
anywhere.
