The goals include enabling uniform data exploration by allowing type patterns for all types, aligning type patterns with instanceof and aligning instanceof with safe casting, and allowing pattern matching to use primitive types in both nested and top-level pattern contexts. The structured concurrency API simplifies concurrent programming by treating groups of related tasks running in different threads as single units of work, thereby streamlining error handling and cancellation, improving reliability, and enhancing observability. The G1 GC proposal notes that although G1, which is the default garbage collector of the HotSpot JVM, is designed to balance latency and throughput, achieving this balance sometimes impacts application performance adversely compared to throughput-oriented garbage collectors such as the Parallel and Serial collectors:
