Java SE 8u92 Nashorn JavaScript Engine No Longer Converts Java Long Type to JavaScript Number Type (Doc ID 2668803.1)

Last updated on JUNE 05, 2021

Applies to:

Java SE JDK and JRE - Version 8 and later
Information in this document applies to any platform.

For example, the result of the following code is changed.
