Thank you for looking into the details of this. If the user who ran into
the issue is using Java, they can fix the issue themselves by relocating our or
their Calcite version locally.
If the user uses Scala, we could look into fixing the issue with a patch to
the shade plugin (maybe using a custom
[transformer](https://maven.apache.org/plugins/maven-shade-plugin/shade-mojo.html#transformers)?)
Since I ran into the issue before I suspect that we'll run into the issue
again.
