Thanks for the update.
I'm happy to say you are the first one to "use/launch" Karaf 5 ;)
About the TomcatURLStreamHandlerFactory is known "issue":
https://github.com/jbonofre/karaf5/blob/main/services/spring-boot-application-manager/src/main/java/org/apache/karaf/springboot/SpringBootApplicationManagerService.java#L110
I have to improve this ;)

The following works:
Karaf.json:
====
{
"applications": [
{
"name": "e3web",
"url": "file:///home/jaap/Karaf5Test/e3web-dev.jar",
"type": "spring-boot",
"properties": {
"enableHttp": true,
"enablePrometheus": true
}
}
]
}
====
Add to Spring boot application:
====
@SpringBootApplication
@ComponentScan
public class E3webApplication {
...
public static void main(String[] args) {
TomcatURLStreamHandlerFactory.disable(); // see
https://github.com/spring-projects/spring-boot/issues/21535
SpringApplication.run(E3webApplication.class, args);
}
====
Start with
java --add-modules jdk.security.jgss -cp

|Hi
|
|No it’s not this because k5 don’t use OSGi for the spring boot launcher. I
still
