Hi,
Because there is no contractual guarantee that any BMP finder
method is free of side-effects, this optimization is not spec
compliant (9.3.2 ...find... invokes a matching ejbFind method).
HOWEVER, the most common case by far will be that checking
the cache rather than calling the bean finder method will lead to
appropriate behavior. I would make this optimization the default,
with the option to disable it for marginal cases.
