I think derby.log is overwritten several times during suites.All anyway,
so that shouldn't be too much of a problem. The engine is also rebooted
a number of times, see for instance DatabasePropertyTestSetup.setUp().
Even if we were able to keep a single derby.log with all the history
from suites.All, it would probably be very hard to find the relevant
part of it because of all the negative tests.
Thank you Knut and Dyre, I'll just add it to suites.All without worrying about this then.
