I'm getting the same warning while preparing the sample-tests, i.e. without running any of my code. Is this Kata currently broken?

    /Flux.java:1: warning: Can't initialize javac processor due to (most likely) a class loader problem: java.lang.NoClassDefFoundError: com/sun/tools/javac/processing/JavacProcessingEnvironment
public interface Flux {Integer getNone();void setNone(Integer i);}

The warning vanishes if I manually load tools.jar at the very beginning of prepare().
