Modify jrecreate to add capability of creating a custom compact profile to generate a minimal jre

A DESCRIPTION OF THE REQUEST :
Even though there already 3 compact profiles defined, that allow generating a jre with smaller footprint, it would be useful to add the capability of generating a jre that contains only the classes that are used by an application. The jre could be generated as part of the compilation.

JUSTIFICATION :
Reduce the footprint (disk and memory) of the jre

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Modify jrecreate so that, instead of accepting as input one of the pre-defined compact profile, the tool takes as input the full path of a jar, infers the list of classes required by thr application and creates a jre that contains only those classes
