The only situation in Ant's current code base where this is ever going to be true is if the jar task has been configured with a filesetmanifest other than "skip".

Will only ever be true in the first pass if the task
performs two passes because doubleFilePass
is true.

public void setRoundUp(boolean r)
Zip archives store file modification times with a granularity of two seconds, so the times will either be rounded up or down. If you round down, the archive will always seem out-of-date when you rerun the task, so the default is to round up. Rounding up may lead to a different type of problems like JSPs inside a web archive that seem to be slightly more recent than precompiled pages, rendering precompilation useless.

If we are going to recreate the archive instead of updating
it, all resources should be considered as new, if a single one
is. Because of this, subclasses overriding this method must
call super.getResourcesToAdd
and indicate with the
third arg if they already know that the archive is
out-of-date.
This method first delegates to getNonFileSetResourceToAdd and then invokes the FileSet-arg version. All this to keep backwards compatibility for subclasses that don't know how to deal with non-FileSet ResourceCollections.
