Ask the JDK Architects
summary
Audience Q&A covers concrete progress and timelines: Sumatra fizzled after joint Oracle–AMD work but the follow-on is Graal compiler work inside Project Metropolis that can emit GPU and vector code; two low‑latency GCs are active (Shenandoah from Red Hat and a proposed ZGC from Oracle); jlink already makes Docker images radically smaller; application class-data-sharing targets Java 10 and Java Flight Recorder/Java Mission Control aim to be open within a year; finalization is deprecated in JDK 9 and removal planning proceeds while Valhalla (value types) and six‑month releases continue.
