Bug 527854

Description Bence Sipka 2017-11-28 06:24:23 EST

Given a class with two templated methods which have the same name:

	public static <T extends TypeMirror> T method(T param) {
		return null;
	}

	public static <T extends Element> T method(T param) {
		return null;
	}

If I try to rename any of the methods with the Alt + Shift + R hotkeys it gives the following error: 
The refactoring 'Rename Method' (org.eclipse.jdt.ui.rename.method) cannot be performed, since its input does not exist.

When I try to edit the method signature (Change Method Signature dialog), and rename the method to something else, BOTH of the methods get renamed, which is not the expected result.
Also, any other operations will result on both of the methods edited. (For example, adding a parameter gets added to both.

Also, when I try to rename the type variable with Alt + Shift + R, the type variable renaming works, but executes on the FIRST declared method.

When I rename the type parameter variable to something else:

	public static <T extends TypeMirror> T method(T param) {
		return null;
	}

	public static <E extends Element> E method(E param) {
		return null;
	}

This way the renaming works as expected.
