lock-on-active is not working as expected.
I seems to work as activation-group.

Works fine with 5.x
Fails with 6.0.0 CR3 and CR4

Fact:

public class Poc implements Serializable {

	private static final long serialVersionUID = 1L;

	private long id = 1;
	private boolean test1 = false;
	private boolean test2 = false;
	private int foundTest = 0;
...
}

Rule:

rule "test1"
lock-on-active 
dialect "mvel"
    when
    	$poc:Poc( isTest1() )
    then
    	System.out.println("test1 found");
    	modify($poc) { setFoundTest($poc.getFoundTest() + 1) }    	
end


rule "test2"
lock-on-active 
dialect "mvel"
    when
    	$poc:Poc( isTest2() )
    then
    	System.out.println("test2 found");
    	modify($poc) { setFoundTest($poc.getFoundTest() + 1) }    	
end

Test:

@Test
public void lockOnActiveTest() {
	// Get the Knowledge base from the DRL file 
	KieSession kSession = getSF();
			
	Poc poc = new Poc();
	poc.setTest1(true);
	poc.setTest2(true);
	
	kSession.insert(poc);
	
	// Fire the rules
	kSession.fireAllRules();
	
	assertTrue("broken",poc.getFoundTest()==2);
	
	// Clean up
	kSession.dispose();
}
