Remove javadoc for overridden methods

[gregw]

There are many methods in the source that have javadoc like:

    /*
     * @see javax.servlet.SomeClass#someMethod()
     */
    @Override
    public Object someMethod()
    {
        ...
    }

We should remove all such empty javadoc as the @Override provides all the information needed.

@joakime @olamy @lachlan-roberts Do you have any awk/sed/scripting magic that can do this?

[joakime]

Not offhand, but I wonder if checkstyle (or some other tool) can detect javadoc that has no content like that?

I tried running a few different regex replaces through Intellij, I'll put a PR up and see how it looks.

Fixed in jetty-10 with PR #4583.
