This has been checked at beginning of JrtfsTestMain. It will quit 
silently if not launched with a JDK 8.  But, it looks checking 'release' 
file is a more light weight solution. I will adjust it. Hope its format 
is identical for all releases.

If you don't mind, how about abstract a super class for "Basic"? Basic 
is a testng test rather than plain java app.
