Progress! The operation registry I was getting the exception from gets
loaded from a GeoTools resource, META-INF/registryFile.jai. The comments
mention that org.geotools.image.jai.Registry.
registerGeotoolsServices(OperationRegistry) needs to be called when using a
custom classloader. That would be great, except the relevant method has
been removed.

Anyone here know what the proper way to register Geotools services is in
geotools 10?
