Re: ACIDity of Prevayler 2.6

in theory nothing can protect 100% against cases you said.

again: atomicity = rollback transaction if it fails.

the thing we dont agree on is the definition of failure. IMHO it's clear in
java: exception

in a language which doesn't have exceptions another definition would be
necessary, such as a negative return value. then it would be identical
behavior to depend on return value of transaction or catch exception thrown
by it or any other code it uses.
