I think it would be reasonable to relax the restrictions on -source 
-target if they match the value for -release.  The main goal here is to 
avoid having to resolve conflicts, but if there's no conflict, there's 
no problem.

I think that allowing the older form of numbers (1.8, 1.7, etc) for 
older releases is OK too, in which case the check between -source and 
-release should (probably) be on the normalized numbers, i.e. although 
perverse, the intent of -source 1.7 -release 7 is clear.
