Migrate the project to Jakarta JAXB 3+

[Spikhalskiy]

When attempting to use the project in an environment with new Jakarta JAXB 3+ the following exception is thrown:

Caused by: java.lang.NoClassDefFoundError: javax/xml/bind/JAXBContext

Would it be possible to switch the project from javax.* to jakarta.* or to create a parallel jakarta variant of the pmml-model module utilizing eclipse-transformer?

Would it be possible to switch the project from javax.* to jakarta.*

You are using JPMML-Model 1.5.X, which is "Java XML Bind" (aka javax.xml.bind)-based.

The upgrade to Jakarta XML Bind (aka jakarta.xml.bind) happened in late 2021, when JPMML-Model 1.6.0 was released.

Currently, the project is being migrated from Jakarta XML Bind 3 to 4 (needed for Java 8 to 11 upgrade). It will be the cornerstone of the upcoming JPMML-Model 1.7.X.

TLDR: Jakarta XML Bind 3 is in the 1.6.X branch, and Jakarta XML Bind 4 is in the master branch. Both work with Glassfish Metro and EclipseLink MOXy runtimes just fine. All releases are always in the Maven Central repository.
