Thomas Wöckinger commented on SOLR-16728: ----------------------------------------- I search for a different org/eclipse/jetty/alpn/client/ALPNClientConnection.class in the whole directory by using following cmd: find -name *.jar -exec jar tf {} \; | grep ALPNClientConnection | less there is only jetty-alpn-client-10.0.13.jar which is containing the class. So this must be something different. The only reason for seems to be two different class loader accessing this class. > ClassCastException while creating new collection using JDK17 > ------------------------------------------------------------ > > Key: SOLR-16728 > URL: https://issues.apache.org/jira/browse/SOLR-16728 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
