ComponentManager error messages in log

[Andrew Stevens <at...@hotmail.com>]

I've got a Cocoon (2.1.7) based application which is working fine, however, 
I've noticed that every ten seconds it's writing the following to the 
core.log:

DEBUG   (2005-07-18) 16:46.23:727   [core.runnable] (Unknown-URI) 
Unknown-thread/DefaultRunnableManager.ExecutionInfo: Executing command

WARN    (2005-07-18) 16:46.23:727   [core.manager] (Unknown-URI) 
Unknown-thread/ExcaliburComponentManager: Attempted to release a $Proxy20 
but its handler could not be located.

Any idea what a $Proxy20 is, and why its handler has gone AWOL?
I'm guessing it's a dynamic proxy that the ComponentManager has used for 
some component or other, and since I've seen similar messages before with 
different numbers after the "$Proxy" I assume that value depends on the 
specific configuration and how many other components happen to be 
initialised prior to the one that causes the problem.

Okay, so it's only a warning, but I'd still like to get rid of it.  Is there 
any way of finding out what component is the cause?  Initially, I assumed it 
would be one of our custom ones since Cocoon is obviously perfect :-)  
However, maybe it could be even more perfect, as I see the same messages in 
an out of the box build (just customised the local.build.properties and 
local.blocks.properties to cut out stuff we don't use) running in the 
bundled Jetty...
