This is a general problem of Service providers in Java. As Lucene only has a single instance in the parent classloader (Lucene is part of Solr's classloader) it only has a single lookup to find analysis components. Your proposal will cause the same problem if other cores. If you unload a core and it removes it's analysis components, the anal is in another core will fail from that point on. To fix this correctly, Solr would need to have a separate Lucene impl per core. This is undoable. In general the per core classpaths in Solr are strange. Codecs, PostingsFormats, DocvaluesFormats and analysis components should be loaded in same classloader like Solr and Lucene itself. There is no solution to this well known problem. -- This is an automated message from the Apache Git Service.
