When we use Web Port Startup Poller with EAP511, the server is not started.
We get an error about the port (8080) already being in use. Which it is not (confirmed with netstat).

When changing Startup Poller to JMX, the server starts as expected.

When using the JMX Shutdown Poller, it also fails. This time with failed attempts to access the JMX server after the server has shut down:

Using Process Terminated Poller works as expected though.
