I have an older app that still runs with zk CE 8.0.2.2. On a Tomcat 8.5 with JVM 11.0.20 I get the following error message:

21-Nov-2023 14:48:27.043 INFO [https-openssl-nio-8443-exec-6] org.zkoss.util.resource.impl.LabelLoaderImpl.loadLabels Loading labels for de

Can someone tell me what the problem is

Regards, Andi
