[Hawkular-dev] Command Gateway - zip file is empty

[Juraci Paixão Kröhling]

Team,

I was working on a change to hservices.t.g.r.c when I noticed a set of 
exceptions, which might have been happening for days now. Basically, 
they seem to be caused by this, for hawkular-command-gateway-war.war:

 > Caused by: java.util.zip.ZipException: zip file is empty

This happens for the latest master, and only on that specific 
environment: it works fine locally on my laptop and works fine on Docker 
for Heiko. I couldn't find a reasonable answer for this.

A consequence is that the command-gateway endpoints are not working on 
that environment, as the deployment failed. The agent, for instance, 
calls the following URL quite often: 
http://hawkular02:8080/hawkular/command-gateway/feed/ .

Does anyone has any idea on what might be wrong? Did I miss something 
from the logs?

Here's a complete server.log:

The OS is RHEL 7.2, but not sure how relevant this is.
