[8u communication] - Removal of jdk8u60-hs and jdk8u60-dev forests

[Seán Coffey]

To help keep the mercurial server clean of old unnecessary development 
forests, I'd like to suggest that the jdk8u/jdk8u60-hs and 
jdk8u/jdk8u60-dev forests be deleted. With 8u60 already GA, these old 
team development forests are no longer required.

If I hear no objections before COB Monday 18th January, I'll ask ops 
team to delete those forests.

regards,
Sean.
