ForceEagerActivationOption and "not()" LHS pattern does not invoke matchCreated listener

Given the following rules

rule ND
when
    not ( Double() ) 
then
    // do nothing. 
end
rule ND2
salience 1
when
    not ( Double() ) 
then
    insert( new Double(0) ); 
end

and KieSession created with ForceEagerActivationOption.YES and a generic AgendaEventListener on fire all rules returns:

 created: 0 cancelled: 1 fired: 1

hence incoherent as matchcreated .

Expected: created=2, cancelled=1, fired=1.

Reporting this as also I understand this eager option is used by jBPM.
