Description

Consider the following:

interface I {
  def foo(bar)
  def foo(bar,baz)
  // ...
}
@groovy.transform.AutoImplement
class C implements I {
  @Override // foo(bar) and foo(bar,baz)
  def foo(bar, baz = null) {
  }
}

We want to auto-implement most of I but explicitly provide an implementation for both foo methods. Compiler says "The method with default parameters "java.lang.Object foo(java.lang.Object, java.lang.Object)" defines a method "java.lang.Object foo(java.lang.Object)" that
is already defined."

Defining the overrides separately (no default generated method) works fine.
