Patch derby-6619 which prints warnings on derby.log if permissions are missing
to get and set the context class loader in SingletonTimerFactory (which can
lead to classloader leak). Also adds a test of this by checking derby.log in
SecureServerTest.

> As part of the fix for DERBY-3745, Derby silently swallows security
> exceptions and leaks class loaders. This can give rise to denial-of-service
> attacks. At a minimum, Derby should report the swallowed exceptions so that
> the security policy can be corrected and the application can be hardened
> against this attack. The swallowing occurs at these locations:
