I just installed Dspace 6 and I'm getting this error message when I launch a webapp. I emailed helix84 off-list (sorry about that!) and he responded that it is a database problem.
He said that: "Both error messages indicate some unexpected problem with the database. > java.lang.NullPointerException > at org.dspace.core.AbstractHibernateDAO.getHibernateSession(AbstractHibernateDAO.java:48) https://github.com/DSpace/DSpace/blob/dspace-6.0/dspace-api/src/main/java/org/dspace/core/AbstractHibernateDAO.java#L48 > java.lang.IllegalArgumentException: Required metadata field 'dc.title' doesn't exist! > at org.dspace.content.CommunityServiceImpl.findAllTop(CommunityServiceImpl.java:166) https://github.com/DSpace/DSpace/tree/dspace-6.0/dspace-api/src/main/java/org/dspace/content/CommunityServiceImpl.java#L166 " I ran both /dspace/bin/dspace database test /dspace/bin/dspace database info and it didn't display any errors. BTW, I couldn't get Dspace to work at all with Tomcat7 or Tomcat8. I eventually tried Jetty9 and that worked.
