Steps to reproduce:
1. Install Matterhorn and run the integration tests
2. "Land and Vegetation: Key players on the Climate Scene" - the dual stream version - fails with
org.opencastproject.workflow.api.WorkflowOperationException: org.opencastproject.mediapackage.NamespaceBindingException: Namespace 'http://www.w3.org/2001/XMLSchema-instance/' is not bound
I'm seeing this every time as well.
The issue is caused by a wrong XML schema instance namespace declaration in some test zip files. The correct declaration does not have a trailing slash.
See http://www.w3.org/TR/2012/PR-xmlschema11-1-20120119/#nss_langids section 184.108.40.206 for details.
I searched the whole code base including all zips and fixed the remaining.
