Java & Developer Productivity
JEP targeted to JDK 28: 540: Simple JSON API (Incubator)
JEP 540 adds a simple, built-in JSON API to the Java platform. It is now targeted to JDK 28 as an incubator feature.
Java has long relied on third-party libraries like Jackson or Gson for JSON, so a standard lightweight API would remove a dependency for common parsing and generation tasks. As an incubator module, the API can still change before it is finalized. Footnotes: JEP = JDK Enhancement Proposal; JDK = Java Development Kit; JSON = JavaScript Object Notation; API = Application Programming Interface.
Show HN: Spens sandboxed, observable coding agents
