[rules-users] viewing working memory

I am working with stateless session (Drools 5.1.1) and I wish to view the objects in the working memory (debug purposes) I understand that in stateless session the audit does not work (not working for me, on breakpoint I get the message "the selected working memory is empty" ). How can I view in breakpoint (or print in runtime) the working memory? Regards, Hezi
