Yes, they are different. Before, a RuntimeException in the PipelineRunner 
would bring down processing of all pipelines. That is changed in CVS so that 
runtime exceptions throws during pipeline processing are logged and do not 
bring the thread down.

The "could not create components" error is not specifically fixed in CVS. 
That error will occur if the amount of time to process a pipeline is longer 
than the interval that the system processes the pipeline *AND* you do not 
have any free threads. Possible solutions are:

a) increase thread pool size
b) increase wait between pipeline processing attempts (currently 1sec)
c) increase wait time for a free thread (currently 1 sec)

I hope that makes (more) sense :)
