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:
<h3>Caused by:</h3><pre>java.lang.IllegalAccessError: class org.apache.solr.schema.ICUCollationField tried to access protected field org.apache.solr.schema.IndexSchema.luceneVersion (org.apache.solr.schema.ICUCollationField is in unnamed module of loader java.net.FactoryURLClassLoader @61639b88; org.apache.solr.schema.IndexSchema is in unnamed module of loader org.eclipse.jetty.webapp.WebAppClassLoader @6a988392) at org.apache.solr.schema.ICUCollationField.init(ICUCollationField.java:128) at org.apache.solr.schema.FieldType.setArgs(FieldType.java:202) at org.apache.solr.schema.FieldTypePluginLoader.init(FieldTypePluginLoader.java:149) at org.apache.solr.schema.FieldTypePluginLoader.init(FieldTypePluginLoader.java:43) at org.apache.solr.util.plugin.AbstractPluginLoader.load(AbstractPluginLoader.java:189) at org.apache.solr.schema.IndexSchema.readSchema(IndexSchema.java:531) at org.apache.solr.schema.IndexSchema.<init>(IndexSchema.java:188) at org.apache.solr.schema.ManagedIndexSchema.<init>(ManagedIndexSchema.java:119) at org.apache.solr.schema.ManagedIndexSchemaFactory.create(ManagedIndexSchemaFactory.java:279) at org.apache.solr.schema.ManagedIndexSchemaFactory.create(ManagedIndexSchemaFactory.java:51) at org.apache.solr.core.ConfigSetService.createIndexSchema(ConfigSetService.java:342) at org.apache.solr.core.ConfigSetService.lambda$loadConfigSet$0(ConfigSetService.java:253) at org.apache.solr.core.ConfigSet.<init>(ConfigSet.java:49) at org.apache.solr.core.ConfigSetService.loadConfigSet(ConfigSetService.java:249) at org.apache.solr.core.CoreContainer.createFromDescriptor(CoreContainer.java:1550) at org.apache.solr.core.CoreContainer.create(CoreContainer.java:1426) at org.apache.solr.handler.admin.CoreAdminOperation.lambda$static$0(CoreAdminOperation.java:92)
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.
