After OpenJDK 8 the separate JRE was deprecated.

The recommendation now is for app developers to include their own JRE with the app; just like how each electron app includes its own copy of chromium.

Since people tested on one JVM version and ran production in another. Finding that gives unpredictables results people moved to linking the versions together. And then the next natural step is distributing the runtime and the app together.

Note this was not possible in the past as the java license prohibited redistribution.

Since mid 2017 when the JRE was discontinued. How else are you shipping Java apps? With the JDK? That’s for developers.
