> BUILDING.txt states that JEXL "requires Java 6 (or later)". I assume that
> you expect "mvn test" to work with Java 11. If not, then this is really a
> doc bug in BUILDING.txt–it should say that it "requires Java 6 (exactly)" or
> include the range of supported Java versions.
>
> *Impact*
> This is a small barrier to entry for a new contributor. There is an obvious
> and straight-forward way to get past the problem, which is to download a
> compatible version of Java and set JAVA_HOME accordingly. I used Java 1.8,
> which already had installed on my dev machine. This prints the same
> warnings, but no errors.
