● Created by the need to deal with existing binary artifacts which reference the pre-Jakarta 9
package names.
○ For example, javax.servlet is now jakarta.servlet.
● The project can transform binary class files and containers of binary class files such as JARs,
EARs, WARs, etc.
○ Also other important resources such as manifests, property files, ServiceLoader
configuration files and other text files
● Rule driven so custom rule sets can be used
○ Jakarta 9 rule set being developed
● Plan to have CLI, Maven and Gradle plugins
