Re: [jboss-dev] Re: jbossas -beans.xml opt
Is there any place (forum or wiki or anything else) where i can read
about its usage or more about where these kind of lazy beans would come
in handy?

Those are the lazy proxies generated by <lazy/>.
We try to use the best lazy mechanism available.
(1) Javassist (allows for class exposure in a proxy)
(2) JBossAOP (although currently if this exists, (1) should too)
(3) JDK dynamic proxies (needs interfaces)
I would need to check if we can avoid the explicit injection,
and use lazy nested directly:
<property name="someProp"><lazy
bean"SomeBean"/></property>

They have a dependency on the "bean", at Not_Installed state.
Meaning the minute "bean" is installed in MC, you can have lazy proxy
for it.
