Tyler Hobbs commented on CASSANDRA-7563:
----------------------------------------

This is almost good to go, but it looks like there are some problems with Javascript in Java

I believe we are considering requiring Java 8 for Cassandra 3.0, so if there's not a straightforward
fix for whatever the underlying problem is, we could potentially just advertise the limitation.

> * is Java Driver as a dependency required ?
> * is it possible to extract parts of the Java Driver for UDT/TT/coll support ?
> * CQL {{DROP TYPE}} must check UDFs
> * must check keyspace access permissions (if those exist)
