 * Plugin of trace sampler CPU policy in the optional plugin folder. Please only activate this plugin when you need to disable trace collecting when the agent process CPU usage is too high(over threshold).
 * Plugin for Spring 6.x and RestTemplate 6.x are in the optional plugin folder. Spring 6 requires Java 17 but SkyWalking is still compatible with Java 8. So, we put it in the optional plugin folder.
