Sylvain Wallez closed COCOON-889:
---------------------------------
Resolution: Fixed
Assign To: (was: Ivan Kurmanov)
There were some nasty multi-threading bugs fixed that were causing NPEs in
pipelines called from cron jobs. So this should be fixed in 2.1.8.
Reopen it *only* if it still breaks with the latest revision.

> The general picture: I use Forrest, which got me 2.1.2-dev version of Cocoon.
> I
> edited the sitemap.xmap to remove unnecesary things, like PDF generation (FO
> processing) and alike. Didn't change pool-* settings.
> In site.xml I have an item with href='/'. This item is referenced in one of
> the
> pages. This quite well might be a Forrest bug, but maybe Cocoon also need to
> be
> more careful about null pointers in this case.
