Java / Java 12

What are the new JVM features in Java 12?

  • Shenandoah garbage collector, an experimental garbage-collection low-pause-time algorithm is added in Java 12 to reduce garbage-collection pause times by performing evacuation work concurrently with the running of Java threads.
  • Promptly Return Unused Committed Memory from G1, starting Java 12, G1 will now check Java Heap memory during inactivity of application and return it to the operating system. This is a preemptive measure to conserve and use free memory.
  • Abortable Mixed Collections for G1, improvements in G1 efficiency include making G1 mixed collections abortable if they might exceed the defined pause target. This is done by splitting the mixed collection set into mandatory and optional. Thus the G1 collector can prioritize collecting the mandatory set first to meet the pause time goal.
  • Default CDS Archives enhances the JDK build process to generate a class data-sharing (CDS) archive, using the default class list, on 64-bit platforms. The goal is to improve startup time. From Java 12, CDS is by default ON.
  • Reduced number of ARM ports, Java 12 removes all sources related to the arm64 port while retaining the 32-bit ARM and 64-bit aarch64. Removal of this port would let contributors focus efforts on a single 64-bit ARM implementation and eliminate duplicate work that would result from maintaining two ports. Currently, two 64-bit ARM ports are in the JDK.
