The JDK we use by default is updated quite frequently, but the required 
JDK version has not intentionally been kept at the latest. This has been 
caused by dependencies creeping in. We can't just blindly update either 
as we have to wait for a Gradle version that supports the new JDK 
version. I think we should keep it well defined through documentation, 
but also make the build use the release flag to force compatibility with 
the documented JDK version.

I will see if I can figure out how to change that in Gradle.
