You cannot lookup components on a disposed ComponentLocator exception

           Summary: You cannot lookup components on a disposed
                    ComponentLocator exception
           Product: Cocoon 2
           Version: 2.1.3
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Major
          Priority: Other
         Component: core
        AssignedTo: dev@cocoon.apache.org
        ReportedBy: John.Webber@jentro.com


We're using Cocoon 2.1.3 and we get this error message regularly in our
development environment (Linux, Tomcat, HSQLDB, JDK1.4.2).  For a typical stack
trace see below. When the exception occurs, the only thing that seems to help is
restarting Tomcat. Googling shows that a few other users have reported this
problem in the past year, but I haven't seen any solution. So far, we've only
seen it in our development environment, not in our production environment
(Oracle 9i). Wish I could give more detailed information as to when it occurs,
but it always seems to strike out of the blue (but usually when we've been
trying out a lot of changes).
We're not using Flowscript, Woody or other blocks, just core Cocoon.

Bertrand Delacretaz added in cocoon-users:

"I've seen this recently on both 2.1.3 and (I think) 2.1.4, but it was very late
on a deadline and I didn't have time to investigate, just found a workaround.

It happened right after making a CVS commit of a sitemap.xmap while Cocoon was
running, and the workaround was to make any change to the sitemap to cause it to
be reloaded. Happened under macosx with JDK 1.4.1. "
