I have spent countless hours troubleshooting different applications. Via the experience I can draw a conclusion about several Java SE features/APIs which most of the developers should just stay away from. When I refer to most of the developers, I have the regular Java EE developers in mind, not to the library designers / infrastructure engineers.
Full disclosure: I do honestly think that in the long run, most of the teams are better off staying away from the following features. But as always, there are exceptions. If you have a strong team and are fully aware of what you are doing, go ahead. In most cases though, if you start including following tools to your arsenal, you will regret it in the long run:
- Reflection
- Bytecode manipulation
- ThreadLocals
- Classloaders
- Weak/Soft references
