jbpm-container tests are failing because of WildFly 23 dependencies misalignment on 7.59.x and main:

java.lang.ClassCastException: com.ibm.ws.tx.jta.TranManagerSet incompatible with javax.transaction.TransactionManager

The root cause is a missing org.apache.geronimo.specs:geronimo-jta_1.1_spec exclusion which was removed by JBPM-9659 pull request.

On main, there is another issue described in RHPAM-3918, which is handled for jbpm-container tests by this issue as well. The fix seems to be removal of xercesImpl from the deployed test archive.
