Subject Re: EJB Life Cycle

I'm not a big java GC expert but...  I think that finalize will only  
be called after the GC has decided your ejb instance is no longer in  
use.  Whether or not the proxy it's holding is still in use will be  
determined separately anyway.  My understanding is that generally  "I  
want to help the GC" code doesn't actually help appreciably and mostly  
gives you more code to install bugs in and maintain.
