Response to: Logging and tracing code

All of those things (security, transactions, clustering) are all great, but any reasonable engineer is going to find a lot of things to be concerned about with this approach.

First, AOP is hacking the byte-code at runtime. This is a huge red flag that if it is really no problem needs to be addressed up front.

Second, can I debug it? Can I step through line by line as the method gets called and the aspects get invoked, then as the main body runs and the aspects are re-invoked, etc.

Third, has this technology ever been used IN PRODUCTION? We have heard a lot about AOP theory and example implementations from PARC, but what about real use on a web application has a healthy amount of tables and real business logic with transactional edge cases?

Plus there are possible interaction issues. What if my security aspect requires a database lookup within a nested transaction aspect? Will it find a read-lock table and go into deadlock?
