Corretto 8, tools.jar (classpath)

[Jim.Freeman]

Is there any point in getting tools.jar into the classpath for Corretto 8 installations w/AppDs agent?

In our AWS Beanstalk automation for instances using OpenJDK Java 1.8, we had a bit of machinery extending classpath to include the JDK's tools.jar (with the understanding that that was required for some of AppD's more advanced features).

But https://docs.appdynamics.com/display/PRO45/App+Server+Agents+Supported+Environments#AppServerAgentsS...

says that at least some advanced features are not available with Corretto 8/11.

So does AppD not utilize Corretto 8 JDK's tools.jar?  If so, how, and for what?

Or is it of no use there now, and we can stop jumping through classpath hoops?

Thanks for any insights.

Hi @Jim.Freeman,

Thank you for posting to the community.

Advanced features such as OIT are available with Corretto 8/11 for the latest java agent.

If you use Corretto 8, which is prior to Java 9, object instance tracking uses tools.jar, so specifying classpath may be meaningful.
