Log: - Changed port validation introduced in commit #308035 to consider negative ports and ports > 65535 as invalid. The tests that fail due to #308035 in the standard ext were not fixed. If the behavior in those tests turns out to be the desirable one, both this commit and #308035 ought to be reverted or at least adapted.
