Why do you now think contrary?

When I read the first part of your message I thought: heck, why is it
a checked exception?
Stupid question: can a OgnlException exception occur on objects in the
cache? I mean in practice...
To my understanding the checked OgnlException occurs before putting
something into the cache. Therefore the CachedException is more or
less an exception which is somehow produced at runtime, due to a
programming error. Sounds like a runtime exception for me, but  I
would love to hear why you are not thinking different
