SMP Error on Acceptance (NAPTR) OpenNCP 9.0.1

When querying the SMP for ISM (or other data) the following error occurs

e.g. for PL java.lang.RuntimeException: eu.europa.ec.dynamicdiscovery.exception.DNSLookupException: Non of the extensions supports Publisher lookup results (e.g. NAPTR services)! The ISM can not be loaded.

For e.g. AT and CZ it is OK

Doing a manual search for PL (ISM query is NOT OK) returns

Doing a manual search for AT (ISM query is OK) returns

Same for CZ -> ISM query OK

So it looks like the problem adressed in issue 440 and the fix in 9.0.1 seems to work only partially (?)
