If nothing else, if you're changing the set of required dependencies, this needs to be documented.  And installing `coreutils` seems to bring in a whole lot of unnecessary stuff.

@jonathan-gibbons my bad, I should have created another PR for this
Regarding documenting changes in dependencies: AFAIK, IDEA project setup is not documented anywhere (at least "IDE support for Java code" section at https://github.com/openjdk/jdk/blob/master/doc/ide.md is WIP). Earlier `idea.sh` required Ant and you wouldn't know about it until it fails at the end of the script :)
So could you please clarify, what do you mean by that?
