Example code:

    public String example(String string)
    {
        if (string == null)
        {
            try
            {
                string = "foo";
            }
            finally { }
        }

        return string.trim();
    }

The hint is incorrectly shown on the trim() call. After removing the try-finally, the hint disappears. (In the original code, the try-finally was because of a lock/unlock operation.)

Maybe the hint implementation treats the finally block like a catch block and believes it would fall through if the code in the try block fails.
