Java Development Kit 15, Oracle’s implementation of the next version of Java SE (Standard Edition), becomes available as a production release today, September 15, 2020. Highlights of JDK 15 include text blocks, hidden classes, a foreign-memory access API, the Z Garbage Collector, and previews of sealed classes, pattern matching, and records.
JDK 15 is just a short-term release, only to be supported with Oracle Premier Support for six months until JDK 16 arrives next March. JDK 17, the next Long-Term Support release, to be supported by Oracle for eight years, is slated to arrive one year from now, as per Oracle’s six-month release cadence for Java SE versions.
