T Jake Luciani commented on CASSANDRA-9402:
-------------------------------------------
Overall, This is an improvement. We spoke offline and addressed a potential
issue with user_function_timeout_policy. Since a Stop-the-world GC could
happen during execution of the UDF.
I'd like to get a professional opinion on this work, since I'm not convinced
you couldn't, for example, access "/etc/password" via Nashorn (since nio is
whitelisted).
