hi, 

you can remove the ProcessInstanceInfo.hbm.xml from META-INF. this file triggers the exception you got.

Duplicate collection role mapping org.jbpm.persistence.processinstance.ProcessInstanceInfo.eventTypes


in my environment, I use JBoss7.1.1 as well.  And I use JPA2 for the jbpm-gwt-console-server.war
The following is what I did
0. remove ProcessInstanceInfo.hbm.xml and persistence.xml from WEB-INF\classes\META-INF
1. extract persistence-JPA2.xml and JBPMorm-JPA2.xml from WEB-INF\lib\jbpm-persistence-jpa-5.3.0.Final.jar to WEB-INF\classes\META-INF
2. rename the persistence-JPA2.xml to persistence.xml
3. add  <transient name="id" /> to <entity class="org.jbpm.persistence.processinstance.ProcessInstanceInfo"/> in JBPMorm-JPA2.xml
4. add the following to persistence-JPA2.xml
<entity class="org.drools.persistence.info.SessionInfo" metadata-complete="false">
           <attributes>
            <id name="id">
                <column name="id" />
                <generated-value generator="sessionInfoIdSeq" strategy="SEQUENCE"></generated-value>
                <sequence-generator name="sessionInfoIdSeq" sequence-name="SESSIONINFO_ID_SEQ" allocation-size="1"></sequence-generator>            </id>
          </attributes>
      </entity>
