Description
While testing an application that uses Calcite, the following error is observed at start-up on a Websphere9 environment (IBM J9 VM, Java8, Ubuntu):
Caused by: java.lang.ExceptionInInitializerError at java.lang.J9VMInternals.ensureError(J9VMInternals.java:141) at java.lang.J9VMInternals.recordInitializationFailure(J9VMInternals.java:130) ...

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).
