AbstractMethodError with outer links

[DarkDimius]

Dotty compiled by dotty has compiled hello world, so I am looking now into more complicated phases:

Exception in thread "main" java.lang.AbstractMethodError: dotty.tools.dotc.transform.PatternMatcher$Translator$OptimizingMatchTranslator.dotty$tools$dotc$transform$PatternMatcher$Translator$MatchTranslator$$$outer()Ldotty/tools/dotc/transform/PatternMatcher$Translator;

How to reproduce: compile dotty by dotty(as part of test suite).
Than compile such file:

object A {
  def main(args: Array[String]): Unit = {
       args match { case Array() => println("empty"); case _ => println(args)}
  }
}

Exception in thread "main" java.lang.AbstractMethodError: dotty.tools.dotc.transform.PatternMatcher$Translator$OptimizingMatchTranslator.dotty$tools$dotc$transform$PatternMatcher$Translator$MatchTranslator$$$outer()Ldotty/tools/dotc/transform/PatternMatcher$Translator;
