Jato migration to jakarta without source code ?

[vharseko]

Due to the lack of the library source code, it is proposed to discuss approaches to migration:

1. Are there sources to restore the code?
2. Replace the namespace with a shade Tomcat Migration Tool for Jakarta EE Software
3. Decompile the source code
   any other ideas?

Many history:
Insecure deserialization in Jato Framework
Jato library incorrectly escapes some URLs
Source code for binary files included in the sources
Jato Binary distribution
OpenAM Jato Shaded Library

There is a transformer-maven-plugin that helps convert libraries without source code from javax to jakarta.
But maybe there is another solution to the issue?
Example usage:

 <plugin>
    <groupId>org.eclipse.transformer</groupId>
    <artifactId>transformer-maven-plugin</artifactId>
    <version>0.5.0</version>
    <extensions>true</extensions>
    <configuration>
        <rules>
            <jakartaDefaults>true</jakartaDefaults>
        </rules>
    </configuration>
    <executions>
        <execution>
            <id>default-jar</id>
            <goals>
                <goal>jar</goal>
            </goals>
            <configuration>
                <artifact>
                    <groupId>${project.groupId}</groupId>
                    <artifactId>${project.artifactId}</artifactId>
                    <classifier>jakarta</classifier>
                </artifact>
            </configuration>
        </execution>
    </executions>
</plugin>

The JATO source code is not available and even if it were, it would be way too outdated to attempt to fix. Decompiling will never yield a perfect result, and is very error prone.
You can also use the transformer-maven-plugin jar goal with jakartaDefaults=true:
