Bug 62062 Mark Occurrences annotation text is not interesting as Tooltip Description
I20040512-0800 Mark Occurrences annotation is not interesting as Tooltip Description. Steps: - enable Mark Occurrences - set caret to a variable and wait until occurrences marked - hover over variable or press F2 -> expected: type, name and javadoc -> was: only name (I guess this is the Annotation's text)
