Project overview
Problem
The install footprint is currently preventing MOXy from being bundled with other software and used on mobile platforms.

Goals
- Reduce the install footprint to 1 MB (from 5.4 MB)
- Be compatible with Project Jigsaw
Concepts
Present any concepts relevant to the feature.
Package Splitting
This is when classes from the same package are distributed among different bundles. This is not compatible with OSGi, an therefore is not something that we can do.
Requirements
The following sections will expand the goals of this project into more concrete requirements.
Design Constraints
All bundles must remain binary compatible except the OXM aspects of org.eclipse.persistence.core.
Design / Functionality
Bundle Changes
New Bundle - org.eclipse.persistence.micro
This bundle will include the all the common classes to both MOXy and JPA.
Modify Bundles - org.eclipse.persistence.moxy & org.eclipse.persistence.core
The OXM classes from core will be moved to MOXy.
Testing

Documentation
The following items will need to be documented:
- What the binary incompatibilities are (if any).
- How to migrate to the new release.
Open Issues
This section lists the open issues that are still pending that must be decided prior to fully implementing this project's requirements.
Issue # | Owner | Description / Notes |
---|---|---|
1 | Peter/Doug | Does the implementation of this feature require us to bump the version number to 3.0? |
Decisions
This section lists decisions made. These are intended to document the resolution of open issues or constraints added to the project that are important.

Future Considerations
During the research for this project the following items were identified as out of scope but are captured here as potential future enhancements. If agreed upon during the review process these should be logged in the bug system.
