[JBoss JIRA] (WFLY-12504) Memoryleak in Metrics-Endpoint

I just want to note I ran the same test I did with WildFly master on WildFly 18.0.1.Final and I did not see the issue there. This is either a new issue or has been resolved.

> I noticed there seems to be a memory leak when calling the /metrics endpoint (with Prometheus). I don't know if this relates to the Keycloak metrics or the general Wildfly base metrics.
> Every request to /metrics seems to consume some more heap memory until a OOME occurs. No other requests are done.
> If the metrics endpoint isn't used at all the server works fine.

[JBoss JIRA] (WFLY-12504) Memoryleak in Metrics-Endpoint

-----------------------------------------
[~thradec] If you are still seeing problems, please file a new issue. Thanks!
> Memoryleak in Metrics-Endpoint
> ------------------------------

> Key: WFLY-12504
> URL: https://issues.redhat.com/browse/WFLY-12504
> Project: WildFly
> Issue Type: Bug
> Components: MP Metrics
> Affects Versions: 17.0.1.Final
> Environment: Docker Image jboss/keycloak:6.0.1
> Reporter: Mathias Werlitz
> Assignee: Richard Opalka
> Priority: Blocker
> Labels: blocker-WF18, fixed_needs_core
> Fix For: 18.0.0.Final

> I noticed there seems to be a memory leak when calling the /metrics endpoint (with Prometheus). I don't know if this relates to the Keycloak metrics or the general Wildfly base metrics.
> Every request to /metrics seems to consume some more heap memory until a OOME occurs. No other requests are done.
> If the metrics endpoint isn't used at all the server works fine.
