It would be nice if the default validation error could provide more guidance here, ie to catch an NPE from DN and convert it into a suitable validation error.
to reproduce:
for https://github.com/estatio/estatio
{code}
git checkout 46739ac06
{code}
then
{code}
mvn clean install -DskipTests
{code}
or (to rerun subsequently):
{code}
mvn install -DskipTests -pl estatioapp/app
{code}
