We are updating from Activiti 5.11 to 5.12.1 on a JBoss SOA-P 5.2 platform.
When we are deploying our web application, which embeds our Activiti, this is now throwing problems during parsing of the BPMN workflow.
Caused by: java.lang.ClassCastException: com.ctc.wstx.stax.WstxInputFactory cannot be cast to javax.xml.stream.XMLInputFactory
at javax.xml.stream.XMLInputFactory.newInstance(XMLInputFactory.java:136)
at org.activiti.bpmn.converter.BpmnXMLConverter.convertToBpmnModel(BpmnXMLConverter.java:191)
at org.activiti.engine.impl.bpmn.parser.BpmnParse.execute(BpmnParse.java:179)
In our unit tests for the workflow it is not causing any problem, so there is some class path clash with JBoss.
How can we run Activiti on JBoss? Excluding the stax dependency from Activiti gives the following exception: Could not retrieve instance of the Activiti process engine: Error parsing XML
