Hello Andrea,

Thank you for the hint. I finally took the gwc repo and started my own Dev
instance to add additional logs for my case.

My problem happens because gwc does not seem to support correctly wms 1.3.0
services, as the one offered by french IGN.

I have created an issue on GitHub (does not seem to have Jira project for
gwc).

Alexandre
