Regression in 1.10.16

Hi all

the eclipse folks have found an issue in 1.10.16, loading JavaEnvUtils
before loading FileUtils fails because there is a cycle of static
dependencies between the classes on Windows now.

I've got a patch and test ready that I'm going to commit once the full
test suite has completed on my machine.

From there I propose to start a release vote for 1.10.17 (or 1.10.16.1?)
and also inform the user list about the problem detected.

The person who reached out to me mentioned several issues, I will spend
a bit of time trying to figure out whether more needs to be fixed before
cutting the release.
