> While the scm address can be a host name (relative to the current search domain) if the
om address is just a hostname and not a FQDN a NPE is thrown:

> I don't know what is the right validation rule here, but I am pretty sure that NPE should
be avoided and a meaningful error should be thrown. (and the behaviour should be the same
for scm and om)
