When a method or constructor is not found (see Lookup*Values for examples) we should describe the signature of the not found element in the exception being thrown (currently the message is "No such method found in class X" or "No such constructor found in class X").
The motivation for this is that, usually, such errors are caused by typos or silly mistakes in the signature of the method/ constructor, and it will make a developer's life easier if one can easily spot what is the signature of the not found method/constructor.
