Mercurial check out for a particular JDK8 build

[Shrinivas Joshi]

Hello,

I have a question regarding mercurial checkout steps. What is the right 
way to check out source for the master and the nested repos (jaxp, 
langtools ..etc) for a particular JDK 8 build from 
http://hg.openjdk.java.net/jdk8/jdk8/ ? I didn't find much luck with hg 
clone and hg update for particular revision/changeset number (705 in 
case of JDK8-b89?). Probably I need to pass the right arguments to 
get_source.sh script but I am not sure what they should be.

Thanks for your help.
