Hello Jean and company, Funny you bring up this issue. I opened a Tomcat Bugzilla (#12968) to suggest protecting o.a.c/o.a.j but Glenn didn't agree with my intentions. You can refer to the Bugzilla description thread for details:
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=12968 I concur that protecting server-specific packages such as o.a.c and o.a.j is the way to go, since they are intended to be inaccessible by untrusted code.
