The decision to implement generics in a backwards compatible way in Java
5 had some immediate benefits, but we are also paying the price today.
It seemed to be done to maintain backward binary compatibility with older
bytecode that could not be recompiled. Was there a lot of such bytecode? I
never realized ...
It was not just a binary compatibility for already compiled
byte code. It would have impacted the ability to recompile
existing source code as well.
Yes - lots of code.
Java got generics in its 6th version (1.0, 1.1, 1.2, 1.3, 1.4, 1.5) and
implemented generics in a way compatible with existing collections.
C#/.NET got generics in its 3rd version (1.0, 1.1, 2.0) and implemented
generics in a way that required new collections to be added.
