In brief: Is there a way of configuring all Ports used by management-agent.jar (introduced in SonarQube 5.5) or even disabling it?
More Info: I'm trying to run SonarQube on OpenShift (again), this time version 5.5/5.6.
On startup I get the following error: Exception thrown by the agent : java.rmi.server.ExportException: Port already in use: 0; nested exception is: java.net.BindException: Permission denied.
What I found out so far is that
- the agent opens three ports,
- where two can be configured (System properties
com.sun.management.jmxremote.portandcom.sun.management.jmxremote.rmi.port) - but one of them is by design always the ephemeral port (port 0), which doesn't seem to work on OpenShift.
In addition to setting the ports explicitly to the allowed range on OpenShift (ports 15000-35530), I tried the -XX:+DisableAttachMechanism option with no luck.
Any ideas how to work around that? Can SonarQube work without the agent?
How to reproduce:
Create an OpenShift app from this, then change the SONAR_VERSION to 5.5 or 5.6 in .openshift/action_hooks/build
