Java 12 General Availability

Mark Reinhold announced today that "JDK 12, the reference implementation of Java 12, is now Generally Available." In that announcement, Reinhold stated that "GPL-licensed OpenJDK builds from Oracle are available" at https://jdk.java.net/12 and that "builds from other implementors will no doubt be available soon." Reinhold's post also summarized the eight features delivered with JDK 12:

• 189: Shenandoah: A Low-Pause-Time Garbage Collector (Experimental)
• 230: Microbenchmark Suite
• 325: Switch Expressions (Preview)
• 334: JVM Constants API
• 340: One AArch64 Port, Not Two
• 341: Default CDS Archives
• 344: Abortable Mixed Collections for G1
• 346: Promptly Return Unused Committed Memory from G1
