CODETOOLS-7902083: Simplify building jtreg

[Jonathan Gibbons]

Maurizio,

If you can do this in a way that makes it optional, that would be 
great.   Having put effort into pruning the set of dependencies, I've no 
desire to see the set creep up again unnecessarily, although I admit the 
usefulness of the plugin.
