Hello,
Based on my understanding of how the manager servlet container instance is bootstrapped, it inherits the configuration of the main embedded servlet container. This prevents users from configuring things such as SSL independently.
I'd like to see the ability to have SSL configured for the main servlet container and no SSL for actuator endpoints. For users not executing in the cloud, the allows the main web application to be protected with SSL, but makes backward facing endpoints used for monitoring tools to consume easier to deal with.
