      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.

          Bug - A problem that impairs or prevents the functions of the product. JBPM-10088 Subprocess rollbacked transaction makes getTimerMappingInfo query fail

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
