A lot of the things you can do with LINQ you can do in Java now there are lambdas and method references. e.g. http://benjiweber.co.uk/blog/2013/12/28/typesafe-database-in...

Properties you could simulate with lambdas now. something like Property<String> name = get(() -> name).set(name -> this.name = name);

You would lose all the existing framework support that assumes getters and setters doing that though.

Some of the generics failure will likely be fixed in 9 (Primitive specialisation). Other things are not as bad as some people think (At least generic supertype params are available at runtime)
