It would seem there is an issue around
{{org.apache.calcite.util.ImmutableBeans}} and the reflection mechanisms that
it uses, in the context of {{RelRule#Config}} (and specifically the default
method {{RelRule$Config.as}}).
Googling a bit, I found the following Flink ticket FLINK-19820, which has a
very similar exception message. In that case it was seen with Java9 in a Debian
environment, and the problem is also around {{ImmutableBeans}} in
{{RelBuilder#Config}}, and again the issue seems generated by a default method
({{RelBuilder$Config.toBuilder}}).
The Flink ticket was closed as "Won't Fix" just because Flink does not support
Java9 (and apparently the issue did not occur with the Flink-supported Java
versions), but the underlying Calcite problem was never tackled (and Calcite is
supposed to work on Java9).
