Daniel Worley commented on SOLR-14151:
--------------------------------------
Apologies for the wrong diagnosis earlier. I debugged some more and noticed
SolrResourceLoader::findClass was never making use of the schemaLoader. I
added the following code to the top of that method and the test will pass using
a packaged class for the encoder on a delimited payload filter. Not sure if
this has other repercussions or if there's something cleaner but I thought I'd
share the findings.
{{if (cname.contains(":") && schemaLoader != null) {}}
{{ return schemaLoader.findClass(cname, expectedType);}}
{{}}}

> * When a package is updated, the entire {{IndexSchema}} object is refreshed,
> but the SolrCore object is not reloaded
> * Any component can be prefixed with the package name
> * The semantics of loading plugins remain the same as that of the components
> in {{solrconfig.xml}}
> * Plugins can be registered using schema API
