Is there a procedure by which you can optimize/shrink/select/obfuscate only 'used by your app' classes/methods/fields from rt.jar provided by Sun by using some optimization software like ProGuard (or maybe other?). Then you would actually be able to minimize the download size of your application considerably and make it much more secure ? Right?

Related questions:

Do you know if Sun's "jigsaw project" which is waited to come out, is intended to automatically handle this particular issue?
Did somebody manage yet to form an opinion about Avian java alternative? Please share it here.

Thank you.
