Do not make it common behaviour to use 'Supports' instead of 'Required'. 
It is only a workaround for this problem. Actually it depends on your 
use case (business behaviour) whether to use 'Supports' or 'Required'. 
Using 'Supports' instead of 'Required' can break some use cases, since 
it results in reading uncommitted data some times. Thus, business 
behaviour is no more deterministic. The benefit you gain is that some 
deadlocks might be away, and access time might be improved.

yes, this is what I'm doing right now, to re-check all the methods
we have in all the beans whether they really need "Required" or just
enough to have "Supports"...

I'll also try "database" locking in our production to see whether
it will helps. I'll report asap.
