what we really need is to identify individual plaforms. I mean
J2SE platform is identified by vendor, major version, minor version.
J2ME uses configuration and profiles. As those informations are
different for different types of platforms it makes sense to
move them to subclasses. And unless we want to test instances
of JP using instanceof we should have a special attribute.

Regarding your question - for some types of projects it makes
sense to limit set of possible plaftorms. For example, a MIDP
project may require at least J2ME, CLDC-1.0 and MIDP-1.0,
assigning of J2SE platform to such project would cause compiler
errors.
