Summary

Update the Java Native Interface (JNI) spec to define JNI_VERSION_19 and change the JNI function GetVersion to return this version.

Problem

JNI is updated in Java 19 to define a new function IsVirtualThread. The JNI function GetVersion needs to be updated to return a version for the updated native interface.

Solution

• Update the JNI spec to define the constant JNI_VERSION_19.

• Update the function GetVersion to specify that it returns JNI_VERSION_19.

• Update the table of the JNI version "included" in each release Java SE 11 to 19.

Specification

A zip file with the diffs is attached. The changes are limited to the "Version Information" section:

• The "Version Constants" sub-section is updated to define JNI_VERSION_19 with the value 0x00130000.

• The function GetVersion is changed to return JNI_VERSION_19 and the table of the JNI version included in each release is also updated.
