Java Runtime

A Java Runtime Environment (JRE, or Java Runtime) is a Java Virtual Machine (JVM), Java platform core classes, and supporting Java platform libraries. It's released as a certain version of a distribution or included with a vendor's product release. A Java Runtime can be installed to run a single Application or to be used by many applications.

A Java Runtime is identified by three attributes:
  • Vendor, such as Oracle Corporation
  • Distribution name, such as OpenJDK Runtime Environment
  • Version, such as 1.8.0_282

When displayed by JMS, a Java Runtime from Oracle indicates if it requires an update.
