Bug 102142 [quick fix] Change method signature quick fix renames parameter
In 3.1. Code: public class Foo { Foo(String string) { System.out.println("" + string); } private void bar() { new Foo(3); } } The compile error on new Foo(3) offers a quick fix: "Change constructor Foo(String) to Foo(int)". Selecting it changes not only the type, but the name of the parameter: String string becomes int i. Accepting this default leads to a compile error.
