Hi Walter, I just tried this out. Yes, it does not work that way. Right now, the driver and datasources are not loaded using the multicore lib aware SolrResourceLoader. Loading entity processors and transformers from the multi core lib should be fine.
Can you please open a JIRA issue for this? However, we may only be able to fix this after 1.3 because a code freeze has been decided upon, to release 1.3 asap.
