> Having many WHEN clauses in CASE expressions in a query yields a error message saying "Query failed: RemoteRpcException: Failure while running fragment., ClassReader.accept() should be called with EXPAND_FRAMES flag".
> (It's not just the number of WHEN clauses in each CASE expression that matters, but the total number.   (Deleting some from either caused the query to work again, and then adding more WHENs in the other CASE expression caused the query to fail again.))
