Indeed, as we've said in other mails, this change is going to expose a 
lot hacks. In this specific case then System.getenv() is specified to 
return an unmodifiable map but a library that Gradle uses seems to want 
to hack into the underlying map so that it can modify it. Stack trace below.

Jochen may be able to find out more about this, maybe there is a 
description somewhere on what the real issue is. It might be something 
that can be tackled in other ways.
