When I saw that closure vars inside Java8 lambdas are final my first thought was that obviously Java is from now on on maintenace and that's it. The language Java won't evolve any more. I guess things will just stay like that from now on as the case for Cobol or something. The focus will be on tools, framewors, systems, etc. as it already has been for a while I fear ...

The problem with "real" closures (i.e. the ones you can write to) is that they require a dramtic change in the underlying mechanics: you need to keep stack frames around for longer than a method call.  Having that in Java would be really nice but the potential for impact on the huge basis of existing code is severe.  I personally like the simplified anonymous classes approach because it is a pragmatic step forward: you get to use anonymous functions with far less visual overhead than before.

Kind regards
