Thats not strictly true about ignoring the JRE as the JDK incorporates 
the JRE and that's what is used to run Java programmes.

Not meaning to be anal about it, but i have had problems in the past 
where I have had things trying to call the wrong version of java and 
left me scratching my head wondering whats wrong :)

An easy way to check is with `which java` which will show you which 
binary is being called by showing the full path.
