-encoding and -source in module-info.java

[Alex Buckley]

The JLS is not going to define syntax for a 'source' declaration and 
then leave it up to compilers to interpret. It is bad enough that the 
JLS defers to "host system" for resolving dependences, and that will be 
fixed with a standard module system configured from the language. We're 
not going to take two steps forward, then one step back.

The idea of explicit source levels _in the language_ comes up every few 
years. I assume people want to use it as a backdoor way of removing 
language features. But that is off-topic for this list.

Sounds good. Please discuss further on compiler-dev, not jigsaw-dev.
