why the Parser/Error Annotation still in glyph
margin  

- New class A
public class A {
    void test(B b) {
        b.test();
    }
}

	A Parser Annotation appears on 'void test(B b) {'
line
	
- New class B
public class B {
    void test() {
        System.out.println("test");
    }
}

- I set 'Automatic Parsing Delay' to 500(more
short time) 
	in Tools->OPtion->Editing->Java Sources->Properties
	
- the red fork/parse error annotation still here

- compile the files successful
- the red fork/parse error annotation still here
- I have to press 'enter' key at the end of that
line and undo it or
  do something like useless actions.

- this time red fork disappeared.

Is there any method to turn away this situation.
