Don't use Anonymous Inner Classes
Added by Federico Vera almost 7 years ago.
Updated almost 7 years ago.
Description
There're some annoying issues when using Anonymous Inner Classes:
- Can't serialize (we actually need this)
- Not easily optimizable by compiler (since methods are overridable they are called using
invokedinamic)
- Code seems confusing for some people.
- Blocks Mejora #749: Hacer que las expresiones sean serializables added
