Find implementation doesn't work on classes

[fbricon]

If you have a class Foo, and a class Bar like:

class Bar {
   Foo foo = new Foo();
}

find implementation on Foo, doesn't find the actual Foo class!

Whether codelenses are enabled and/or only working for interfaces/abstract classes should not affect the explicit calls to search for implementations

[snjeza]

Could you try the following:

class Bar {
   Foo foo = new Foo() {};
}

For this case, if the class doesn't find any subtype, then go to definition instead.
