I would say that toString() must correspond to serialize(), not the other way
around.
The code in HyperlinkRecord.serialize is correct. If a link is URL and not a
UNC path then the moniker field MUST be set. If it is null then you are
constructing wrong data.
HyperlinkRecord.toString() uses slightly different logic and prints the moniker
if it is not null and hyperlink type is URL (UNC path option is not tested
here). This is not quite correct but acceptable because toString() is used
mainly for debugging purposes.
In any case, I'm not going to change it without a unit test that demonstrates
the NPE issue. If you are able to construct one, please upload and re-open this
ticket.
