<spring.version>5.3.20</spring.version>
<zk.version>9.6.0.1</zk.version>
<zkspring.version>3.2.0</zkspring.version>
in zk.xml,use the iceblue_c theme
<library-property>
<name>org.zkoss.theme.preferred</name>
<value>iceblue_c</value>
</library-property>
when i run Application or use mvn spring-run, my web app can startup, but the theme cannot take effect,there is a UiException when startup:
org.zkoss.zk.ui.UiException: Unknown listener: class org.zkoss.theme.iceblue_c.ThemeWebAppInit

but if I use this command:
spring-boot:run -Dspring-boot.run.fork=false
to startup my web app, there is no exception throw, the theme work well, I search on google why,but cannot find anything help, is anybody have the same problem?
FYI since there is at least two reported issues with similar error stacks / messages, I have created a ticket to centralize this debugging: https://tracker.zkoss.org/browse/ZK-5245
Hi MDuchemin, I tried to boil down my example to a minimum and surprisingly the problem arises as soon as I add
restart.include.zklibs=/z[\w]+-[\w\d-.]+.jar
to file META-INF/spring-devtools.properties in order to get the labels reloaded after a soft restart (caused by spring-devtools).

Not sure why the class fails to resolve, but it looks similar to this question:
https://forum.zkoss.org/question/73399/unknown-listener-errors/
A bit old, but they seem to have a similar issue.
Based on that, do you tomcat endorsed directory? or other elements mentioned in that previous question?
when I change to springboot(zkspringboot),this issue occurs.if I use the traditional web style app (xml based config files in webapp/WEB-INF) and jettty server,there is no problem.

jack3dot1415 ( 2022-08-08 10:49:54 +0800 )editthat's interesting, because fork should only cause a new JVM to be spun up to host the running application. do you have some global arguments in your JVM, maybe using JAVAOPTIONS or similar? Another test would be to check if this happen in other machines also, to rule out config issues.
