Claus Ibsen resolved CAMEL-23448.
---------------------------------
Resolution: Fixed
> camel-launcher jolokia fails to attach agent — JAR path unresolvable from
> nested Spring Boot JAR
> --------------------------------------------------------------------------------------------------
>
> Key: CAMEL-23448
> URL: https://issues.apache.org/jira/browse/CAMEL-23448
> Project: Camel
> Issue Type: Bug
> Components: camel-jbang
> Affects Versions: 4.18.1
> Reporter: Salvatore Mongiardo
> Assignee: Salvatore Mongiardo
> Priority: Minor
> Fix For: 4.18.3, 4.21.0
>
>
> When running `camel-launcher jolokia <name>`, the Jolokia agent fails to
> attach to the target JVM:
> {code:java}
> ERROR: Cannot execute jolokia command due: Error while loading Jolokia agent
> to a JVM process {code}
> *Root cause:*
> _OptionsAndArgs.lookupJarFile()_ in the Jolokia library resolves the agent
> JAR path via:
> _OptionsAndArgs.class.getProtectionDomain().getCodeSource().getLocation()_
>
> This works when camel-jbang runs via JBang (dependencies are real files in
> ~/.m2/repository/), but fails with camel-launcher because:
> # camel-launcher is packaged as a Spring Boot executable JAR using
> camel-repackager-maven-plugin
> # The Jolokia JAR is nested inside
> BOOT-INF/lib/jolokia-agent-jvm-<version>-javaagent.jar
> # getCodeSource().getLocation() returns a jar:file: URL pointing inside the
> fat JAR
> # VirtualMachine.loadAgent() requires a real filesystem path — it cannot
> load an agent from a nested JAR
