--------------------------------

Scott, what do you think? Is it relevant anymore? I'd prefer not to spend time on this since I don't this is a big deal, per se. :-) But if it is, I can do it.

> The RemoverTask of the org.jboss.ejb.plugins.LRUStatefulContextCachePolicy performs removal of passivated beans based on a maxBeanLife - maxBeanAge diff. This is invalid for beans passivated due to size. The calculation should be maxBeanLife - (the per bean instance time of inactivity). The reason is a bean may be passivated very quickly due to cache size constraints and  if the maxBeanLife - maxBeanAge == 0, just a quickly thrown away.
