Hi Stian,
Thanks for the response. How do you know that it belongs to sun.jdk module? I googled but I couldn’t find anything in regards to that.
I managed to get through all the issues, the last stage is adding the log and now I am stuck again. I’m asking how you find the module name because now I am getting Caused by: java.lang.NoClassDefFoundError: org/jboss/logging/Logger error.
I tried adding <module name="org.jboss.logging.jboss-logging”/> to the module.xml but that didn’t solve the problem.
Kind Regards,
Sarp Kaya

If you need additional dependencies in your provider please deploy it as a module, see docs and examples on how to do that. For the missing class you're module definition would need to include:
...
<dependencies>
<module name="sun.jdk" export="true" >
<imports>
<include path="sun/misc/Unsafe" />
</imports>
</module>
</dependencies>
...

Hi,
I am trying to extend an event listener and the example one works fine, which just prints out every event.
However I want to do something more complicated than that. So I added two more dependency on top of keycloak dependencies:
com.codahale.metrics:metrics-core and com.readytalk:metrics3-statsd
In my IDE I was able to develop fine, then maven packages it fine. I package it by including all the dependencies (so JAR file is like 6 MB), otherwise it won’t have the dependencies (I have tried that and it complained at the runtime saying it doesn’t have the class).
Then I start the keycloak service, it starts fine. I get an exception throw like below when I initially use the service (which is when the first event trigger happens):

I don’t know what could be wrong. When I googled the java.lang.NoClassDefFoundError with Keycloak I found that there was an error with Facebook integration. So I am wondering whether this is something similar and a bug with Keycloak? If not then what have I missed?
Kind Regards,
