So Method reference are not really suited to Liseners. I think it's a 
shame since it was a really good use case of method reference.

Since the behaviour of equals is redefined in every class, I don't think 
it is possible.

It may be possible to have a special attribute .methodReference (like 
".length" or ".class", I don't know the official name) returning a 
Method object if the reference was set by reference conversion, null 
Methods like "removeListener" would not work out of the box, but It 
might be updated to support method references.

for exemple:

Runnable method1 = this::myMethod;
Runnable method2 = this::myMethod;
System.out.println(method1.methodReference.equals(method2.methodReference); //returns true
