Rules fail to fire if we create a different ksession through custom workItemHandler in BPMS 6.0.3

Issue

We are using custom workItemHandlers used in BPMN processes. These workItemHandlers are registered in the kmodule.xml, like as:

 <kmodule xmlns="" xmlns:xsi="">
  <kbase name="kbase" default="true" eventProcessingMode="stream" equalsBehavior="identity">
    <ksession name="ksession" type="stateful" default="true" clockType="realtime">
      <workItemHandlers>
        <workItemHandler type="new com.sample.test.handler.TestHandler()" name="Test"></workItemHandler>
        <workItemHandler type="new com.sample.test.handler.TestHandler2(ksession)" name="Test2"></workItemHandler>
      </workItemHandlers>
    </ksession>
  </kbase>
</kmodule>

The first handler uses a new ksession created from kieContainer based on a specific release Id:

KieServices kServices = KieServices.Factory.get();
ReleaseId releaseId = kServices.newReleaseId("com.sample.xyz", "test-test", "1.0");         
KieContainer kieContainer = kServices.newKieContainer(releaseId);       
KieBaseConfiguration kbaseConfig = kServices.newKieBaseConfiguration();
KieBase kbase = kieContainer.newKieBase(kbaseConfig);   

KieSessionConfiguration ksessionConfig = kServices.newKieSessionConfiguration();
ksessionConfig.setOption(ClockTypeOption.get("realtime"));      
session = kbase.newKieSession(ksessionConfig, null);
...
session.fireAllRules(); 

The issue is with the first handler,after the call session.fireAllRules() rules from decision table rules don't get fired. The second handler works fine without issue.
