Get two classes A and B with the same method like: Duplicate string literals warning is raised for "Hello" entries. Correct. Alt+Enter / Introduce constant. Notice the name of the class in the "Introduce to class" dialog's field. Let it be class A. Now go to class B. Alt+Enter / Introduce constant on duplicated literal. Class A is suggested. Change to class B. Set "Replace all occurances" OFF (user wants to process just class B). Ok in dialog. Result: new constant is defined in class B, but the only replaced occurance is in class A. Seems to be wrong. If user asks to process the only occurance, (s)he probably thinks about one located in the editor before dialog invocation. Current behaviour may also produce incompilable code if user chooses private visibility in the dialog.
