Sylvain Lebresne commented on CASSANDRA-8241:
---------------------------------------------

For what it's worth, I do think the lack of auto-boxing will be a pain in the ass. Not to say that I have the perfect solution.

> 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.
