I would like it to be ported to OpenJDK.
Time ago, if I remember correctly, there was a JS engine in JDK 8.
I remember that I knew this because NetBeans could use it to render the Java API website and made reference to it.
I think that its low adoption in the market, and the massive use of more viable solutions, even in the JVM itself (GraalJS) discouraged the port to OpenJDK. This is one of the things I hate in the java ecosystem, along with the XML-hell, the huge disparity between VMs.
About the XML, I am a XML supporter.
I didn’t like when the DOM exploration was deleted in the JDK after Java 8 in support of only SAX one.
Edited: the DOM exploration can be integrated as it was with a libray hosted by the Apache foundation, without change of the original code more than the package import route.
Edited 2: BTW, thank you cutie.
A pleasure. I haven’t worked with SAX, so I don’t know much about it, but it was very unfair to give support only to it.
