----------------------------------------
> Thinking a little more I'm not sure the network server removing its security

I'm pondering more about how to best solve this issue. How about having some
way of triggering this behavior, a property or something else, that would only
be used for the purpose of testing with EMMA? If property X is set, the network
server removes the security manager right before doing shutdown, but only in
the case were it has installed a security manager itself with the default
policy.
What is the view on adding such an interface (property or similar) to the
product, which is only intended for testing purposes?

> It is a bit tricky to use EMMA to measure code coverage for the derby testing.
> Modifications must be made to the source both to avoid problems with the
> SecurityManager and individual tests. It would be good if these modifcations
> could be done once and for all so that it was easier for anyone to run the
> tests with EMMA.
> It would also be good to have ant tasks that would make it even easier to run
> the tests with EMMA.
