APM Agent won't load in WebLogic 14.1

Hi,

We get the following exceptions while trying to load APM agent 24.3 in WebLogic 14.1:

java.lang.IllegalAccessError: class jdk.jfr.internal.SecuritySupport$$Lambda$225/0x0000000800979c40 (in module jdk.jfr) cannot access class com.singularity.ee.agent.appagent.entrypoint.bciengine.FastMethodInterceptorDelegatorBoot (in unnamed module @0x2205a05d) because module jdk.jfr does not read unnamed module @0x2205a05d

 java.lang.IllegalStateException: Unable to perform operation: create on weblogic.diagnostics.instrumentation.InstrumentationManager

 

The WebLogic managed server won't start after throwing these exceptions.

Any insights on what might be causing these errors?

Thanks,

Roberto

Hi @Roberto.Barnes,

I did some digging around and found someone who discovered a workaround.

The workaround that has solved this temporarily by adding the following java option:
--add-reads jdk.jfr=ALL-UNNAMED

If the community does not jump in and provide any insight, you can also contact Cisco AppDyanmics Support
