Extending the JastAdd Extensible Java Compiler to Java 7

• JastAddJ is an extensible Java compiler, implemented using reference attribute grammars. It has been shown previously how the language constructs of Java 5, like generics, could be modularly added to the original JastAddJ compiler that supported Java 1.4. In this paper we discuss our experiences from extending Jast- AddJ to support Java 7. In particular, we discuss how the Try-With-Resources statement and the Diamond operator could be implemented, and how efficient the resulting Java 7 compiler is regarding code size, compilation time, and memory usage.
