I am just upgrading our Solr/ManifoldCF system. During the upgrade process i
tried to raise Solr to version 9.0.0. Unfortunately this results in the
following error, caused by the ManifoldCF Solr Plugin
(apache-manifoldcf-solr-8.x-plugin-2.2.jar):
Caused by: java.lang.IncompatibleClassChangeError: class
org.apache.solr.mcf.ManifoldCFSearchComponent$CloseHandler has interface
org.apache.solr.core.CloseHook as super class

At the moment, ManifoldCF Solr plugins are available up to Solr version 8
Is there a plan, to create a solr-9x plugin version in order to support solr
versions >=9 ?
Kind regards,
Uwe
