I configured the javaagent for the springboot application with the exact steps in the Getting Started wizard, however, when I start the spring boot application, I am getting below error. The agent is not getting started and the application is not getting detected by appdynamics. Can you please help resolve. Thanks.
Java 9+ detected, booting with Java9Util enabled.

Hello @Akshit.Chaturvedi.,
I followed up with some people and I was told this.
Download agent JDK8+
https://accounts.appdynamics.com/downloads
Turns out the Installer Wizzard was sending people to an older download.
Please let me know if that works for you.
Thanks,
Ryan, Cisco AppDynamics Community Manager

Hi @Ryan.Paredez ,
We are already using JDK8+JVM ver 22.12.0.
01-17-2023 10:29 PM
To provide more context this is the exact error:
```
'orgCache' threw exception; nested exception is java.lang.IllegalAccessError: class jdk.jfr.internal.SecuritySupport$$Lambda$1168/0x0000000100f17440 (in module jdk.jfr) cannot access class com.singularity.ee.agent.appagent.entrypoint.bciengine.FastMethodInterceptorDelegatorBoot (in unnamed module @0x1996cd68) because module jdk.jfr does not read unnamed module @0x1996cd68
```
It seems `com.singularity.ee.agent.appagent.entrypoint.bciengine.FastMethodInterceptorDelegatorBoot` class (which comes from AppD) has been placed inside an unnamed module, if that module could given a name, we could access it and deploy our service.

Please try adding this
--add-reads jdk.jfr=ALL-UNNAMED

Thanks for your suggestion @Ryan.Paredez ,
I think giving jdk.jfr access to all unnamed modules is a security flaw, it would be appreciated if the module containing com.singularity.ee.agent.appagent could be a given a name in the next patch.
Thanks!

Even after adding the argument we still see the issue? Any update on how to fix this?
