Hello Erik,

On macosx, the tar.gz distribution usually has the java home dir in 
"jdk-9.jdk/Contents/Home". The -z and --strip-components flags for tar 
probably works well with gnu tar, but we can only rely on that on Linux 
and Windows. You need to write the unpack logic compatible with both 
Solaris and bsd tar as well (yes, that means piping with gunzip and 
manually finding the correct java home dir inside the exploded file tree :).

I would also like to see a better failure handling of a non existing 
file/directory given to --with-boot-jdk. As it looks now, tar is going 
to crap out.

Otherwise the idea seems decent enough.
