Description

I've tried to recreate Solr 8 configuration in Solr 9, but the following part in the config causes an error when creating core. (not SolrCould environment, if it matters)

<fieldType name="text_gen_sort" class="solr.ICUCollationField" locale="" 
numeric="true" strength="primary" multiValued="true" />

The following paths has been added in the solrconfig.xml:

<lib path="..../solr/modules/analysis-extras/lib/solr-analysis-extras-9.0.0.jar" />
<lib path="..../solr/modules/analysis-extras/lib/icu4j-68.2.jar" />
<lib path="..../solr/modules/analysis-extras/lib/lucene-analysis-icu-9.0.0.jar" />

and I checked, that the paths to jars are correct.

The stack trace is lengthy, here the relevant part of it:

Previous configuration with the same 3 libraries and the field type worked. I used bin/solr create_core -c my_core -d my_configset. The change is in the managed-schema.xml. (It used to be just manages-schema in Solr 8, but I recreated the configuration from the new default.)

This looks to me like some kind of a bug. What can be the cause of this and how to overcome the problem?

(I've also created SO question on this - https://stackoverflow.com/questions/72416721/how-to-configure-icucollationfield-type-in-solr-9 )

 

To recreate, just add the above mentioned parts to solrconfig.xml and managed-schema.xml (from _default ) and try to create a core using the configset.
