      I've attached a reproducer.
      kjar - test03644977
      Spring Web app - spring-jbpm-web.war

      To reproduce the issue:

      1. install the kjar
      mvn install

      2. deploy the spring-jbpm-web.war to jboss eap 7.4

      3. a. open browser to access http://localhost:8080/spring-jbpm-web
      b. click New deployment
      c. fill com.redhat.rhpam:test03644977:1.0.0-SNAPSHOT
      d. click Deploy
      e. click Process Definitions
      f. click testTimer2
      g. fill 0 in the Value field
      h. click Start process instance
      You should see the ClassCastException in eap log file

      This issue only occurs in the latest version 7.13.4 (7.67.0.Final-redhat-00024).
      The issue seems to be coming from the SpringRuntimeManagerFactoryImpl [1]:

      System.setProperty(TX_FACTORY_CLASS, SPRING_TX_FACTORY_CLASS);
      TransactionManagerFactory.resetInstance();
      TransactionManagerFactory transactionManagerFactory = TransactionManagerFactory.get();
      if (transactionManagerFactory instanceof KieSpringTransactionManagerFactory)

      { ((KieSpringTransactionManagerFactory) transactionManagerFactory).setGlobalTransactionManager(applicationContext.getBean(AbstractPlatformTransactionManager.class)); }

      It sets the KieSpringTransactionManager as the global transaction manager.

      However, the ejb timer requires a jta transaction manager [2]:

      JtaTransactionManager tm = (JtaTransactionManager) TransactionManagerFactory.get().newTransactionManager();

      This line of the code is where the ClassCastException is thrown.

      How to make ejb timer work with the Spring integration? In another word, how can SpringRuntimeManagerFactoryImpl work with a jta transaction manager required by the ejb timer?

      The following are some considerations about the possible solution:

      1. Simply remove this highlighted line from method SpringRuntimeManagerFactoryImpl(ApplicationContext applicationContext)
      System.setProperty(TX_FACTORY_CLASS, SPRING_TX_FACTORY_CLASS);

      And for setting this variable to be left to user by passing in the jvm for which TransactionManagerFactory to be used, default being "org.drools.persistence.jta.JtaTransactionManagerFactory"

      OR

      2. String factoryClassName = System.getProperty("org.kie.txm.factory.class", "org.drools.persistence.jta.JtaTransactionManagerFactory");

      &

      Providing a setter variable for SPRING_TX_FACTORY_CLASS in class SpringRuntimeManagerFactoryImpl, to be passed as bean property will be helpful or leaving it to user for setting this system property.
