Rules are not fired in business process after upgrading to BPM Suite 6.4

Issue

We have a conditional flow and the condition for one of the flows is rule based (for example TypeHolder(type=="TYPE1")). After we update our installation to version 6.4 the flow rule seems to never be activated. We start our processes using commands, for example:

KieServices ks = KieServices.Factory.get();
KieContainer kc = ks.newKieClasspathContainer();
KieCommands commandsFactory = ks.getCommands();
KieSession ksession = kc.newKieSession();
List<Command> commands = Arrays.asList(
        commandsFactory.newInsert(new TypeHolder("TYPE1")),
        commandsFactory.newStartProcess("org.example.TestCondition")
);
BatchExecutionCommand batchCommand = commandsFactory.newBatchExecution(commands);
ksession.execute(batchCommand);

What could be wrong?
