I can't get into details but I speak about one of the most important Internet services provider
(in 2012: 2,4 G€ revenue, 6000+ employees almost same 
number of contractors, Market Cap in 2015: 7.40 G€)
The idea is if your servers cannot connect to the Internet (but Internet can connect to them)
you are already safer. They have of course also several 
firewalls layers, etc. (not really fun to work with)

Thanks Taher, seems we have almost our workaround already documented :)

Yep, I thought about that. I needed to extract only the OFBiz related libs for OWASP-DC but
with OFBIZ-7930 it's no longer needed.
This nicely completes the point above!

I agree, from a developer perspective Gradle is the best build system I know.
Also a good tool for a sysadmin/devops as long as your GRC allows them https://en.wikipedia.org/wiki/Governance,_risk_management,_and_compliance
