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

Last updated on JUNE 01, 2020

Applies to:

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

Symptoms

With Java SE 8 update 92 and later versions, passing a 'long' type value from a Java object to a JavaScript 'Number' type no longer works correctly.  It gets passed as an 'object' type, causing an incorrect value in the JavaScript Number.

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