> Reverting to Java 11 eliminated the error.
> It's worth noting that the error messages are opaque - there's no specific
> indication that the problem is a version incompatibility. While there is a
> reference to supported Java versions in the [installation
> page|https://arrow.apache.org/docs/dev/java/install.html] of the
> documentation, it's easy enough for that to be missed in favor of the README.
> It could be useful to also codify supported versions through [maven
> enforcement|https://maven.apache.org/enforcer/enforcer-rules/requireJavaVersion.html],
> supplying a less opaque error message when an incompatible Java version is
> used..
