--------------------------------------------------------------
Not sure [~julianhyde], but maybe WebSphere is to blame here.
WebSphere environment in this test was:
{noformat}
WebSphere Platform 9.0.0.1 ... [JAVA8 8.0.3.11]
{noformat}
I have found several issues on IBM involving {{IllegalAccessException}} around
{{java.lang.invoke.MethodHandles$Lookup.checkAccess}}
Particularly this one seems very, very similar at stack trace level:
https://www.ibm.com/support/pages/apar/IV96259
According to IBM's ticket, this got fixed on *8.0.4.10*, so maybe a WebSphere
update is just the solution, and there is no issue on Calcite side. I'll try to
confirm this point.

> 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).
