Java 10 - Overview
Java 10 is a major release in Java release cadence and it was releasd on March 10, 2018. With Java 10, Oracle has changed the java release cadence to a new model, a 6 month release cadence and LTS model for Oracle Java SE products. LTS model stands for Long Term Support model.
From Java 10 onwards, Oracle releases a new version of Java after every 6 month where each version contains one or two major features. Oracle uses a release train concept. Each release train is scheduled for 6 months. Features which are developed within this timeline are shipped in the release otherwise the features are moved to next release train.
Oracle JDK vs OpenJDK
Most of the Oracle JDK binaries are propriety and licensed by Oracle and have multiple restrictions on redistribution. Whereas OpenJDK is more developer community friendly. From Java 10 onwards, Oracle has decided to promote OpenJDK as primary JDK to facility community based development of Java. Oracle will keep producing its own JDKs but it will release them after 3 years and term them as LTS version. So OpenJDK binaries will be released after every six month.
OpenJDK is cloud and container friendly as it can freely distributed as part of the container. So Oracle's move to promote OpenJDK makes java more friendly towards cloud or container development and deployment.
Java 9 and Java 10 are non-LTS release. Java 11 release is a LTS release.
