Nashorn and Java versions

[ahenket]

When your jdk is >= 15, you will get an error for Nashorn when you run a build script:

bootstrapFromGithub.build:
Java 15 has removed Nashorn, you must provide an engine for running JavaScript yourself. GraalVM JavaScript currently is the preferred option.

BUILD FAILED

.../Nictiz-testscripts/lib/Nictiz-tooling-testscripts/generate/2.7.0/ant/build.xml:85: Unable to create javax script engine for javascript

However ... when you actually have GraalVM, this does not go away:

% java -version
java version "21.0.2" 2024-01-16 LTS
Java(TM) SE Runtime Environment Oracle GraalVM 21.0.2+13.1 (build 21.0.2+13-LTS-jvmci-23.1-b30)
Java HotSpot(TM) 64-Bit Server VM Oracle GraalVM 21.0.2+13.1 (build 21.0.2+13-LTS-jvmci-23.1-b30, mixed mode, sharing)

On macOS for ARM there's version 8, and then version 17 and up. There's no version 9-16 anymore (they were never compiled). On version 1.8 I get:

BUILD FAILED
.../Nictiz-testscripts/src/build-multiple.xml:11: The following error occurred while executing this line:
.../Nictiz-testscripts/src/bootstrap-from-github.xml:64: The following error occurred while executing this line:
.../Nictiz-testscripts/lib/Nictiz-tooling-testscripts/generate/2.7.0/ant/build.xml:123: java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal

The way I currently solved this, is by adding https://repo1.maven.org/maven2/xml-apis/xml-apis/1.4.01/xml-apis-1.4.01.jar to my ant/lib folder.

It would be ever so nice be able to use idk >= 15 worry free
