Noting changed in jboss-web.xml at least not to referencing security domain.
In any case i would recommend using 7.1 version of schema https://github.com/jboss/metadata/blob/master/web/src/main/resources/schema/jboss-web_7_1.xsd
but that should not change behaviour.
But there ware changes to security subsystem and some login modules...
is it possible to enable bit more logging for security?
Yes, Tomaz, changing version 7.0 to 7.1 doesn't help. Nothing appears in the console, nothing is in server.log.
Which catagories should I log with DEBUG or TRACE log level?
add trace to org.jboss.security and org.jboss.as.security
Thank you very much, Tomaz! I had a typo in database column name... Now all Arquillian tests are passing :-)
