[jboss-jira] [JBoss JIRA] (DROOLS-3337) ClassCastException while using SessionPseudoClock

[Mario Fusco (Jira)]

     [ https://issues.jboss.org/browse/DROOLS-3337?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-3337.
---------------------------------
    Resolution: Explained


You're creating the KieSession in the wrong way.

If you do 

{code}
KieBase kbase = kieContainer.getKieBase("rules");
KieSession ksession = kbase.newKieSession(null, env);
{code}

the session is not under the control of the kiecontainer and then cannot take the conf in kmodule file. Conversely if you create the kiesession directly from the container like in:

{code}
KieSession ksession = kieContainer.newKieSession("ksession-rules", env);
{code}

then the session can be initialized with what defined in the kmodule file.

Note that your reproducer was wrong anyway because you missed to specify clockType="pseudo" in the kmodule.xml
