Jenkins "Execute SonarQube Scanner" Seems to Ignore JDK

[Stefan Bodewig]

Hi

I'm trying to set up SonarQube for the Ant project
<https://builds.apache.org/job/Ant-Master SonarQube> using the "Execute
SonarQube Scanner" but it always fails because of an
UnsupportedClassVersion exception - so it must be using Java7 or earlier
and not the Java8 I've configured explicitly.

Any ideas?
