Outer.java

public class Outer {
    public class Inner {
    }
}

Fail.scala

object Fail {
  val o = new Outer
  val i = new o.Inner
}

Result:

$ javac -parameters Outer.java 
$ scalac -cp . Fail.scala 
error: error while loading Inner, class file './Outer$Inner.class' is broken
(class java.lang.IndexOutOfBoundsException/0)
Fail.scala:3: error: Fail.o.Inner does not have a constructor
  val i = new o.Inner
          ^
two errors found

This is a 2.12 regression, it works fine in 2.11.8. Java version is 1.8.0_121
