> 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..
