I'm with Eric on the subject of Jimple. Why is an intermediate
representation that is designed as an intermediate language for compiler
optimisation a good choice for the semantic basis of pointcuts? If you
literally allow every Jimple statement to be a joinpoint shadow, then they
become sensitive to the order of expression evaluation and the fact that
Jimple chooses to inline JSRs (to name two examples off the top of my
head). I agree that the AspectJ set is poorly defined, but any principled
replacement has to have a firm basis in one or both of the Java
specification and the JVM specification.
