Java Reflection

[wallymathieu]

It feels like a big important topic for frameworks and generic code in Java land. Reading Jackson source code and seeing the reflection code is interesting.

There is the reflection library:

Question is why Jackson and other libraries don't take a dependency on that? One reason could be due to the ergonomics of using it. One other reason could be due to the pain in taking on a dependency (however benign). Another reason could be the cost of switching out a working solution without a clear benefit (if there is a community consensus around reflection libraries then it would be easier). Capturing the needed knowledge that has been caught in reflection based libraries is probably not an easy thing.
