Java, Today and Tomorrow
summary
Overview of recent and upcoming Java work: Amber adds local variable type inference (var), raw string literals, switch expressions, and records for concise immutable data; Loom prototypes fibers and continuations showing a Jetty demo where fibers produce steady ~100 ms responses instead of 1.5 s spikes with threads; Valhalla value types cut a 500×500 complex-matrix multiply from ~3.6–4 s and ~4 GB allocations to ~260 ms and ~4 MB, raising instructions-per-cycle from ~1.1 to ~2.9.
