Here's the error message:

Ah. Been pretty focused on the binary compatibility of the library jar;
we make no such guarantees for compiler. Obviously that's not good
enough -- at the last, "compiler-interface" needs to retain binary
compatibility. This provides further motivation to establish better
boundaries in the compiler jar. I think this will take a bit of time.
(Fixing the error shown above is easy, but the question of what needs to
retain compatibility and the verification that it is indeed compatible
is more uncertain.)

There are lots of implicit objects/conversions within sbt which handle
compatibility issues within the compiler. I think this is fine for now
and we can do the same for the above error.

I opened a ticket, https://issues.scala-lang.org/browse/SI-4838
