Background Information
I have a Spring Boot web application using Actuator for the production utilities.
The application works fine, and the management port works great. I can browse statistics, check health etc. I also enabled the remote shut-down endpoint, and it properly shows up in the localhost:{mgmt_port}/actuator list of endpoints.
My Problem
When I go to localhost:{mgmt_port}/shutdown though, I see:
<Map>
<timestamp>1453905900007</timestamp>
<status>500</status>
<error>Internal Server Error</error>
<exception>org.springframework.web.HttpRequestMethodNotSupportedException</exception>
<message>Request method 'GET' not supported</message>
<path>/shutdown</path>
</Map>
Useful Information
The whole application still seems to be running after hitting the shut-down link. I can still pull data from my custom application endpoints.
The management URL provided by Spring actuator also seems to still be running fine after hitting shut down.
