Is it legitimate to extract data from Java VM Specification document?

Question

I'm planning to write a bytecode viewer for Java 17 classfile, and distribute my work under some permissive license.

In order to keep consistent my implemenation, I'd like to link my code to Chapter 4 of the Java Virtual Machine Specification (JVMS) in some way. The JVMS seems licensed under Appendix A. Limited License Grant .

According to the answer for my previous post, I may not include the JVMS document file in my work directly. But linking to the JVMS may be possible.

So I have twofold plan.

Firstly, HTML parser program load the page, extract data from the specification, and transform it to skeleton code. For example, the parser extract information from <pre class="screen"> tags and convert it to method calls.

Secondly, I would add some functionality to the skeleton code.

Then, is it legitimate to publish my works in a permissive licnese, possibly include both the parser and the skeleton, or the skeleton only?

Answer 1

The license of this specification does not allow you to create derivative works.

What you plan to do is to create a derivative work ("extract data from the specification, and transform it to skeleton code. [...] add some functionality to the skeleton code.").

If you did what you plan, you would be in breach of the license.
