Even though aspect technologies are very powerful. Especially to address cross-cutting concerns like transactions, it shouldn’t be used everywhere it’s possible.
The first part of this post consists of a simple example that uses AspectJ to return an unexpected value. The last part is about where aspects fits and where you should consider to avoid it.
A quote from the Spider-Man movie:
With great power comes great responsibility
This applies to some degree to aspect technologies too. Since it can change the behaviour of an application at compilation, startup or at runtime. Even without leaving a trace in the source code.
