>
> The most-recent change to both Profiling pipelines (revision 503964 in
> February 07) added the configuration "sax-stream" option and this was done by
> additionally implementing the Configurable interface. But as in
> BaseCachingProcessingPipeline (a base class) the interface Parameterizable is
> already implemented, and an Avalon component can be either one or the other
> [1], this is a bug. It's critical since the cache is retrieved in
> BaseCachingProcessingPipeline.parameterize(), but as Configurable has
> precedence over Parameterizable [2], the cache will be null and a NPE will be
> thrown during generation phase.
