Wrong bytecode generated for trait's method with throws clause

[scabug]

Compiling the following trait with 2.12.0 vs 2.12.1 produces different bytecode

trait Actor {
  @throws(classOf[Exception]) // when changing this you MUST also change ActorDocTest
  //#lifecycle-hooks
  def preStart(): Unit = ()
}

Classfile produced with 2.12.0:

Compiled from "A.scala"
public interface Actor {
  public static void preStart$(Actor) throws java.lang.Exception;
  public void preStart() throws java.lang.Exception;
  public static void $init$(Actor);
}

Classfile produced with 2.12.1:

public interface Actor {
  public static void preStart$(Actor);
  public void preStart() throws java.lang.Exception;
  public static void $init$(Actor);
}

Note how the signature of method preStart$ is different.

Just in case you wonder (as I was), the change in the bytecode do not break binary compatibility.

See chapter 13.4.21 in https://docs.oracle.com/javase/specs/jls/se8/html/jls-13.html

Likely culprit: scala/scala#5570

@throws is an annotations and annotations are not added to static super accessors anymore...

Could you elaborate why the signature for the synthetic static forwarder is problematic? This is for scalac's internal use only.

@dotta said:
My bad, it's likely not a problem. The change in signature does not break binary compatibility, and I don't see any other reason why it could be problematic. I'm closing the issue, sorry for the noise.

No worries, thanks for giving this some additional scrutiny and reporting!
