Daniel John Debrunner commented on DERBY-3445:
----------------------------------------------
Thinking a little more I'm not sure the network server removing its security
manager is a good idea. It would allow any code in shutdown hooks to have free
use of the jvm.
A better long term solution would be to allow a set of policies to be added
into the network server's default set. E.g. could add this policy file:
grant codebase "... path to emma jars" {
// permissions needed
}
This would then be logically added into the permission set that Derby installs
automatically.
> Make it easier to use the EMMA tool to measure the code coverage of the Derby
> testing

> 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.
