We updated our products to Java 11 a little while ago, but I have managed to
dig out an example from before that change. This is from an older version of
the same product, still with Derby 10.14.2.0 and Java 1.8_161:

Just for completeness sake, what does the stack trace look like on Java 8? The
posted stack trace mentions modules, so it must have been generated on JVM 9 or
later.

Richard N. Hillegas commented on DERBY-7114:
Thanks for the detailed stack trace. I am not an expert in this code. It looks
like Derby has confused a PageKey with a ContainerKey while scanning a btree
index. A PageKey contains a ContainerKey (along with a page number). A PageKey
is definitely not a ContainerKey and I would expect a ClassCastException if
Derby attempted this illegal operation.
This definitely looks like a Derby bug, but without a repro, I cannot speculate
any further or offer any workaround. Maybe someone who knows more will weigh in.
