I wasn't aware that Java doesn't provide any API to modify ZIP archives, that's
a shake :-(
Do you think it would be doable if the request would be to create the zip
archive once at the time the archive should roll. I guess the concept of
rolling should be twofold - the log files roll independently of the archives
and the archives roll every n archive rolls. The moment the archive rolls all
logs should be archived.
In case of %d{yyyy-MM-dd}.%i.zip pattern on every change of %i the next log
would be created (no archiving happens at this time) and on the change of the
date the rolling should happen as usual but also all the %i logs created on the
previous date should be archived.
Do you think I can create a ticket for such a feature?

Tom
