My proposal would be: If you start javac with "-source 1.8 -target
1.8" and don't pass a bootclasspath, it should switch to "-release 8"
for convenience. What do you think? Alternatively allow source and
target when passing release if it's not incompatible.
I'd prefer to defer to Jan/Jon on this as they have a statement in JEP
247 to say that -release is incompatible with these options. In any
case, it does feel like the tools needs to take -release into account.
If -release is specified then Gradle shouldn't be added
-source/-target. This may be a timing thing as JDK 9 is still in
development and it always takes time for the tools to catch up.

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.
