Summary of implementation requirements
Prev	Appendix C. Implementation Notes

This summarizes the requirements of our implementation of AspectJ. For more details, see the relevant sections of this guide.

The invoking code must be under the control of ajc for the following join points:
- call join point
- get join point
- set join point
The declaring/target code must be under the control of ajc for the following join points and inter-type declarations:
- execution join point
- adviceexecution join point
- handler join point
- initialization join point
- preinitialiaztion join point
- staticinitialization join point
- perthis aspect
- pertarget aspect
- declare parents
- declare method or field (see interface caveats below)
Implementation Caveats
- The initialization and preinitialization join points do not support around advice
- The handler join point does not support...
  - after advice
  - around advice
  - cflow(handler(..))
- Declaring members on an interface in an aspect affects only the topmost implementing classes the implementation controls.
- cflow and cflowbelow pointcuts work within a single thread.
- Runtime ClassCastException may result from supplying a supertype of the actual type as an argument to proceed(..) in around advice.
