Robert Stupp updated CASSANDRA-8241:
------------------------------------
Attachment: 8241-ecj.txt
Patch that uses Eclipse compiler
([ecj-4.4.jar|http://search.maven.org/#artifactdetails%7Corg.eclipse.jdt.core.compiler%7Cecj%7C4.4%7Cjar]).
Also in my [git branch|https://github.com/snazy/cassandra/tree/8241-udf-ecj]
for this ticket.
Eclipse compiler is pretty fast for our use case. Code is basically copied from
Tomcat and adopted for UDF needs and some code re-formatting.
> 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.
