Claus Ibsen commented on CAMEL-8748:
------------------------------------
Thomas do you have a link to that unit test that causes this problem?
Its maybe starting up / initializating camel and dozer in a bit different way
that we do on unit tests + karaf we have at Apache Camel. It seems it tries to
create a new dozer converter class using a default no-arg ctr. But none of
these converter classes has that, neither the ones that are out of the box from
Dozer itself.
