--install-dir parameter specifies directory where your app will be 
installed. Its value is interpreted differently on Linux, OSX and Windows.
On Windows the value should be relative path. The absolute installation 
path will be constructed from %ProgramFiles% and the value of 
--install-dir parameter.
If --install-dir parameter is not specified, installation directory will 
be constructed from app name. In your case if --install-dir parameter 
will not be set, the installation directory will be %ProgramFiles%\HalfPipe.

You can find ROOTDIR in .cfg files generated by jpackage. However this 
doesn't mean that using ROOTDIR outside of .cfg files is recommended.
Semantics of ROOTDIR can be changed or it can be removed in the future 
versions of jpackage.
There is APPDIR in public jpackage interface with semantics that will be 
stable across jpackage versions going forward.
APPDIR also hides differences between app image layout on Linux, OSX and 
Windows. On Windows and OSX APPDIR resolves in $ROOTDIR/app, on Linux in 
$ROOTDIR/lib/app.

Great.
