You can still use Java 6 and Scala 2.11.
It's just that Java 6 will not receive any bug fixes or security updates, and Scala 2.11 will not either. But both will continue to work.
Seems very sane to me.
I didn't.

Oh, I'm pretty sure that Scala 2.11 will receive fixes, security updates and even backports of features for a very long time. For example SI-2712 is getting back-ported to Scala 2.11.9 and there's even talk of back-porting it to Scala 2.10.
Maybe we'll see longer support for people who don't migrate (heck, SBT still uses 2.10.x), but justifying it by Java version is weird.
If you're okay with using old Java versions, it's not much of a stretch to say you'll be okay with old Scala versions.
Thanks for your support!
No, because Scala doesn't offer forward binary or source compatibility. Maintainers of widely-used Java libraries can write and build for Java 6 and be confident their libraries will be usable by everyone (on Android and off). Maintainers of widely-used Scala libraries have no such option (for now they can write their code using the subset that works in Scala 2.11 and 2.12 and cross-build, but there's no guarantee that such a subset will be maintained in 2.13 and beyond).
There's no guarantee about Java either. This class compiles with Java 7, but not with Java 8:
class SampleClass {
static class Baz<T> {
public static java.util.List<Baz<Object>> sampleMethod(Baz<Object> param) {
return null;
}
}
private static void bar(Baz arg) {
Baz element = Baz.sampleMethod(arg).get(0);
}
}
Ok, but you can compile it with the newer compiler by passing -source 1.7, right? And you can call into it from 1.8 code?
