Exception in AbstractProcessingPipeline.release

[Jochen Kuhnle]

Hi,

I get the following Exception when Cocoon processes a request:

org.apache.cocoon.ProcessingException: Unable to remove component from 
automatic release: component not found.
        at 
org.apache.cocoon.components.EnvironmentDescription.removeFromAutoRelease(CocoonComponentManager.java:789)

The component here being the processing pipeline. This happens because 
InvokeContext.getProcessingPipeline adds the pipeline conditionally:

        if (this.isBuildingPipelineOnly) {
 
CocoonComponentManager.addComponentForAutomaticRelease(this.pipelineSelector, 
this.processingPipeline, this.pipelinesManager);
      }

Wheras AbstractProcessingPipeline removes itself unconditionally:

    public void release() {
        try {
            CocoonComponentManager.removeFromAutomaticRelease(this);
        } catch (ProcessingException e) {
                ...
        }
    }

Since the Exception occurs with each request, this wastes valuable log 
space ;) So I would like to fix this. The question is, how? The hack 
solution would be to not log the exception. The better solution would be 
to somehow tell AbstractProcessingPipeline if it has to call 
removeFromAutomaticRelease.

But.. Upon digging deeper... This whole automatic release stuff is used 
only once in all of Cocoon -- for the ProcessingPipeline. So maybe there 
is a way to get rid of it completely? Any suggestions?

Jochen
