Select the Thread Correlation Mode

You can select the thread correlation mode used by the agent using the async-instrumentation-strategy property within the app-agent-config.xml configuration file.
To run the applications in the Constructor mode, modify the value of async-instrumentation-strategy property, or use the following java command-line option: 
-Dappdynamics.async.instrumentation.strategy=constructor
The system property takes precedence over the configuration file. You cannot change the configured thread instrumentation mode during runtime.
