The code hint "Add @throws tag" for a generic exception shows up, even if I already added the tag.
The following code reproduces the problem:
The hint appears at the line with the method declaration. The JavaDoc `throws` tag is already defined, and yet the hint appears or doesn't go away. If I click on the hint entry in order to apply it, another `throws` tag is inserted, leaving the following code:
Still, the hint is visible.
Obviously, the expected behaviour is that the hint is not visible if the `throws` tag exists for this particular generic exception type.
