Robert Stupp commented on CASSANDRA-8241:
-----------------------------------------
Using Oracle's {{JavaCompiler}} API implementation requires installation of a
JDK (not a good option).
We can bundle the Eclipse thing (which btw also implements the {{JavaCompiler}}
API beside its native API.
I see three options for this one (preferably option 3):
# stick with javassist (effectively resolving this ticket as 'later')
# use ecj with its native API (stick with ecj)
# use ecj with {{JavaCompiler}} API (allows to use ecj and JDK)
> 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.
