The PR #211 introduced changes where the abstract investigator testIpAddress()
would return other Status, which previously only returned null, Up or Down. In
this patch we introduce a new Status "Unknown" that replaces null's semantics.
The important changes #211 introduced was the debugging statements as semantically
the changes would work same as the consumers of testIpAddress() method only used
if returned values were Up or Down and in other cases (null, Alert etc) it would
simply continue to loop through the resources being investigated.
Keeping the debug logs, this commit only replaces the previously returned null
values with Status.Unknown and fixed the debug statements to reflect the same.
In case of trapped exceptions too, we return Unknown status but log the exception
we trapped.
server: add null assertions and remove dead code with testIpAddress usage
This closes #222
