The session management code has been completely replaced with new code in 
3.1M1.  It has rather sophisticated XML-Node base configuration system 
that, unfortunately, goes completely ignored by the tomcat server.  The 
relevant lines are in org.apache.tomcat.session.StandardSessionManager 
starting at line 113:
             try {
                 ((Lifecycle) manager).configure(null);   <===== null 
configuration
                 ((Lifecycle) manager).start();
             } catch (LifecycleException e) {
                 throw new IllegalStateException("" + e);
             }

Since the entire configuration system seems to be the object of some debate 
right now, I propose the following patch in the interest of keeping the 
server operable in the interim:

  }

+            }
         }
         return sessionManager;
      }

The effect of this change will be that the defaultSessionTimeOut set in the 
server.xml context tag will actually be the defaultSessionTimeOut.  Since 
session time out is important (and IMHO the default 60 seconds is way to 
low), I humbly beg that one of the committers make this or an equivalent 
fix soon.
