Christian Beikov commented on CALCITE-2079:
-------------------------------------------
It depends on whether we add automated tests to verify this. I'm not sure how
an automated test could look like, but I guess it'd involve starting a separate
JVM and excercising it a bit to ensure no exceptions are thrown due to class
loading issues. It's certainly possible, but since dependencies change
seldomly, I'd personally also be ok with not having tests for that and doing a
quick fix release in case something was missed. What do you think [~julianhyde]?
