Description
**[Maxim Kovalenko](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=JIRAUSER307822)** opened **[SUREFIRE-2287](https://issues.apache.org/jira/browse/SUREFIRE-2287?redirect=false)** and commented
According to [JEP 451](https://openjdk.org/jeps/451) in JDK 21, the dynamic loading of agents is allowed but {**}the JVM issues a warning when it occurs{**}:
```java
WARNING: A {Java,JVM TI} agent has been loaded dynamically (file:/u/bob/agent.jar)
WARNING: If a serviceability tool is in use, please run with -XX:+EnableDynamicAgentLoading to hide this warning
WARNING: If a serviceability tool is not in use, please run with -Djdk.instrument.traceUsage for more information
WARNING: Dynamic loading of agents will be disallowed by default in a future release
```
In some future Java releases, the dynamic loading of agents will be disallowed by default.
Please add the "{_}agent{_}" ("{_}javaagent{_}" or "{_}dynamicAgent{_}") parameter to the
_configuration_ definition that will be translated to _-javaagent_ option during tests execution.

Contributor guide
Research direction
Start by tracing the configuration definition used during tests execution and how its parameters become JVM options. Implement the agent, javaagent, or dynamicAgent parameter so it translates to -javaagent, then verify the resulting test execution configuration against the JEP 451 behavior described in the issue.
