This exception occurs at the applications that contain <session-config> or <login-config> in the web.xml.

When I reverted the code back to the revision 1137764, I got no exception.

Regards.

Oops, sorry. Revision 1137764 is not correct. "1137693" is correct revesion.

Thanks for the report. The unit tests picked up a similar issue. The problem was caused by r1137753. Investigating now...

Comment 3 Mark Thomas 2011-06-21 11:11:05 UTC

This has been fixed in 7.0.x and will be included in 7.0.17 onwards.
