Description

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.
