[rules-users] CPU Spike creating a StatefulKnowledgeSession using OSGi

[David Conde]

Hi Pavel,

I've changed it over to use a stateless session and I'm seeing the
same behavior. I've done some debugging and it seems to be very slow loading
up the SessionConfiguration due to all of the loading that happens in
ChainedProperties.

Thanks,
Dave
