Description Michael Schierl 2006-02-10 15:22:35 EST

Take the following example (in a java1.5 enabled project):

package enumbug;

public class EnumBug {
	
	public static enum Foo {foo, bar, baz}

	public void bar(Foo f) {
		switch(f) {
		case Foo.baz:
		case  // <-- invoke context assist here!
		}
	}
}

It is incorrect since you may not qualify enums in a switch statement. Now try to complete the next case with context assist.

Resulting exception:
