All comms over jmxmp fail, so the `JmxFeed` doesn't get its sensor values. This
can cause entities (such as `Tomcat8Server`) to show as failing to start.
Here's a simple blueprint to reproduce:
{noformat}
location: centos7_aws_useast1
services:
- type: org.apache.brooklyn.entity.webapp.tomcat.Tomcat8Server
id: tomcat
brooklyn.config:
webapp.enabledProtocols:
- http
- https
jmx.enabled: true
jmx.password: <snip>
webapp.https.ssl:
keystorePassword: password
keyAlias: tomcat
keystoreUrl:
