Bug 81980 Unexpected unresolved enum quick fix suggestions [quick fix] [5.0]
Although the create field and create constant in my enum type suggestions for the quick fix in the code listed below compiles and works fine. It is not quite what I expected for the use of enumerated types. public class EnumQuickFixBug implements Runnable { private State state; private enum State {begin, end}; public void run() { state = State.begin; // Try quick fixing the line below state = State.middle; state = State.end; } public static void main(String args[]) { EnumQuickFixBug bugs = new EnumQuickFixBug(); bugs.run(); System.out.println("Done"); } } I expected to declaration of the enum type to change to something like: private enum State {begin, end, middle}; but instead it did something like this: private enum State {begin, end; public static State middle;};
