Stewardship: the Sobering Parts
summary
Describes stewarding Java for ~9 million developers and billions of lines of code, trading change for compatibility; Java 8 adds lambdas implemented by converting to functional interfaces and using invokedynamic so compilers don’t bloat the VM, and adds Streams with easy parallel streams and retrofitted decomposable collections that actually work; autoboxing creates overload ambiguities solved by strict vs loose applicability; future VM work names Valhalla (value types, specialized generics) and Panama (native interop).
