Mark Struberg commented on OWB-444:
-----------------------------------
Maybe my proposal was not yet clear enough: I like to keep those utils as
members in BeanManagerImpl (with back-references), so for each WebApp we have
exactly 1 BeanManagerImpl. And this has exactly 1 instance of each util. In
this case we do not need any singletons anymore. Because our BeanManagerImpl
has exactly the one needed (and correctly configured) util class at hand.
To give you a few numbers: on a large JSF page I originally had more than 1
million WebBeansFinder invocations! Most of them come from our utils which most
times need to resolve the BeanManagerImpl... I then at least removed redundant
BeanManagerImp.getManager() calls and also removed the doPrivileged and now we
are down to ~400.000 invocations. At the end of the day this still costs up to
20% of our performance, so I would not underestimate the effect!
