Remove 1.8 class files warning

[lucaswerkmeister]

Java 7 has reached end of life, and there aren’t any known Java 8-specific issues, so I suggest we remove the following warning:

warning: It looks like you are using class files from a Java newer than 1.7.
  Everything should work well, but if not, let us know at https://github.com/ceylon/ceylon-compiler/issues.
  In the near future, the Ceylon compiler will be upgraded to handle Java 1.8.

because it’s now obsolete.

Well, I could remove it, but I'd have to replace it with "actually you can't compile to Java 8 bytecode so you can't use default methods"

[FroMage]

Moving to 1.3.

[gavinking]

Huh?!

I think we should remove this warning. It's very annoying and useless.

[lucaswerkmeister]

I agree. Being unable to use default methods is just another interop problem, there’s no need to warn people about it every time they compile anything at all (even if it’s pure Ceylon code).

[gavinking]

Or, y'know, give them an error if and when they try to call a default method.

[gavinking]

I mean, a problem with the current warning is after seeing only about 1k times, I still didn't know I couldn't call default methods in Ceylon.

[FroMage]

Well, I did suggest to change the error message, but nobody answered.

[jvasileff]

+1 for eliminating the message.

The impression I got from this warning when I first saw it was 180º off - that Ceylon might be stale and lacking momentum.

I think it's fine letting folks discover that ceylon compile can't compile newer Java sources on their own, without the bad marketing and compromised UI.

[lucaswerkmeister]

Can we please remove this warning? “Everything should work well, but if not, let us know” sounds like a cover-our-asses statement because we didn’t test whether we work on 8, which isn’t true at all – by now, we’re very sure that everything we support also works on Java 8. A warning that we don’t support lambdas would be more fitting on an import java.base "8" statement in my opinion. (Though then it would suck that you can’t import java.base without warnings.)

[FroMage]

OK fine.

[FroMage]

Done, halleluia
