Benjamin Lerer commented on CASSANDRA-8241:
-------------------------------------------
I think it would be good to define a bit more the scope of the problem. My
understanding is that so far we only use code generation for UDF. Is there some
other place where we use it?
If not, I think it would be nice to have something better that javassist, but
it is only a nice to have and we can stick with javassist for now. From a
benefits/problems point of view it looks as the best choice.
> Use javac instead of javassist

> Using JDK's built-in Java-Compiler API has some advantages over javassist.
> Although compilation feels a bit slower, Java compiler API has some
> advantages:
> * boxing + unboxing works
> * generics work
> * compiler error messages are better (or at least known) and have line/column
> numbers
> The implementation does not use any temp files. Everything's in memory.
> Patch attached to this issue.
