Fixed version (ground truth):

    syntheticAccessor=binding.getAccessMethod(isSuperAccess());
    return;
  }
  if (binding.isPrivate()) {

      syntheticAccessor=((SourceTypeBinding)binding.declaringClass).addSyntheticMethod(binding);
      currentScope.problemReporter().needToEmulateMethodAccess(binding,this);
      return;
    }
  }
 else   if (receiver instanceof QualifiedSuperReference) {
    SourceTypeBinding destinationType=(SourceTypeBinding)(((QualifiedSuperReference)receiver).currentCompatibleType);
    syntheticAccessor=destinationType.addSyntheticMethod(binding);
    currentScope.problemReporter().needToEmulateMethodAccess(binding,this);
    return;
  }
 else   if (binding.isProtected()) {
    SourceTypeBinding enclosingSourceType;
    if (((bits & DepthMASK) != 0) && binding.declaringClass.getPackage() != (enclosingSourceType=currentScope.enclosingSourceType()).getPackage()) {
      SourceTypeBinding currentCompatibleType=(SourceTypeBinding)enclosingSourceType.enclosingTypeAt((bits & DepthMASK) >> DepthSHIFT);

    }
