Aspect-oriented programming enables programmers to modularize the implementation of crosscutting concerns. Linguistic approaches to AOP, like AspectJ, use programming language mechanisms to support the new kind of modularity. We present a Fluid AOP approach, which supports modularization of crosscutting concerns in the development environment. The idea is for the IDE to temporarily shift a program to a different structure to allow some specific editing or reasoning task, and then let the program relax back to its primary decomposition. In this demonstration we present Fluid AJ, a simple Fluid AOP tool built on Eclipse, which modularizes the editing of crosscutting concerns in plain Java code.
