JGroups subsystem logs "version is missing in the configuration file" warning without a log code on deployment using JPA 2LC ---------------------------------------------------------------------------------------------------------------------------- Key: WFLY-13657 URL: https://issues.redhat.com/browse/WFLY-13657 Project: WildFly Issue Type: Bug Components: Clustering Affects Versions: 20.0.1.Final Reporter: Paul Ferraro Assignee: Paul Ferraro Priority: Minor This warning without a log code is logged upon deployment of application: {code} 13:06:16,312 WARNING [org.jgroups.conf.XmlConfigurator] (ServerService Thread Pool -- 101) version is missing in the configuration file {code} I can see this with several EAP Quickstarts, the exact list from CD20 is: batch-processing, bmt, cmt, greeter, hibernate, kitchensink, kitchensink-jsp, kitchensink-ml, managed-executor-service, spring-greeter, spring-kitchensink-basic, tasks-jsf, thread-racing Not sure if it's relevant, but I have noticed all the above mentioned QS use H2. None of the QS that don't use H2 has the warning logged. This can be reproduced with [WildFly 20 Final release|https://wildfly.org/downloads/] and [WildFly 20 Final QS|https://github.com/wildfly/quickstart/tree/20.0.0.Final] as well: 1. Start the server with {{$JBOSS_HOME/bin/standalone.sh}} 2. Deploy one of the above mentioned QS with {{mvn clean package wildfly:deploy}} This warning was not present in CD19 and earlier releases. The same warning was also logged on startup, which has been fixed with JBEAP-19734 and WFLY-13590.
