> I put a breakpoint in org.jboss.tools.jmx.jolokia.JolokiaConnectionWrapper.verifyServerReachable() to see which exception it was and it is a "503 Service Unavailable"
> in this case the "response" is null
> 2 possibilities:
> - it is normal that it is null in this case Jboss Tools need to handle this case
> - it is not normal that it is null and in this case, it needs to be reported upstream (even if a null check might nice as a workaround for now)
