Yup, here it is: 13.4.15. Method Result Type Changing the result type of a method, or replacing a result type with void, or replacing void with a result type, has the combined effect of deleting the old method and adding a new method with the new result type or newly void result (see §13.4.12 <https://docs.oracle.com/javase/specs/jls/se7/html/jls-13.html#jls-13.4.12> ).
For purposes of binary compatibility, adding or removing a method or constructor m whose return type involves type variables (§4.4 <https://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.4>) or parameterized types (§4.5 <https://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.5>) is equivalent to the addition (respectively, removal) of the an otherwise equivalent method whose return type is the erasure (§4.6 <https://docs.oracle.com/javase/specs/jls/se7/html/jls-4.html#jls-4.6>) of the return type of m.
