Release Review

Release: 

Object Teams 2.2.0

Description: 

The Object Teams Project provides tooling for developing highly modular evolvable software using the language OT/J

  • compiler and runtime for OT/J based on the JDT compiler
  • comprehensive IDE for OT/J based on the JDT
  • extension for executing OT/J code within Equinox

Release 2.2.0 of the Object Teams Development Tooling (OTDT)

  • Improved refactoring support
  • Extended code formatting support to handle all constructs of OT/J
  • Bugfixes
  • No incompatibilities to previous releases
API Certification: 

The project leadership certifies that the APIs in this release are "Eclipse Quality".

Architectural Issues: 

No architectural changes since 2.1.0.
With 9 plug-ins written in OT/J, OTDT is a mature self-application of our own technology.
Bugzilla balance since the 2.1.0 release:

  • 66 bugs fixed
  • 1 bug closed as duplicate
  • 1 bug closed as worksforme
  • only marginal increase in open issues:
    • bugs from 30 to 31
    • enhancement request from 13 to 19

Installing OTDT together with other technology that also uses bytecode weaving may currently cause failures in either tool. Efforts have been launched to re-implement the Equinox integration to

  • Leverage the new standard WeavingHook
  • Establish compatibility with other weavers (notably: from AspectJ).

These efforts will receive special attention during the Luna cycle. By cooperating with the authors of the existing org.eclispe.equinox.weaving bundle we'll try to establish a common platform providing mutual compatibility as best as we can.

Security Issues: 

No known security issues

Non-Code Aspects: 

Documentation is hosted at http://www.eclipse.org/objectteams/documentation.php, including

  • many wiki pages: introductory texts, examples and patterns and much more
  • developer guide (also bundled as a help plug-in)
  • OT/J language definition
  • ...

The tool ships with learning material in various forms:

  • installable examples
  • cheat sheet
  • developer guide
  • OT/J language definition
  • new&noteworthy

 

Usability: 

Continued improvements, and adoption of upstream improvements.

End of Life: 

Nothing has been deprecated.

Standards: 
  • No standard exists for OT/J, the project provides the only implementation for this technology
    • Language definition (OTJLD) is maintained at objectteams.org.
    • OTDT 2.2.0 implements OTJLD version 1.3.1
  • OT/J is executed on a standard Java virtual machine
  • OT/Equinox runs on the Equinox framework using ...
    • only standard OSGi headers in MANIFEST.MF
    • only regular extensions in plugin.xml
    • AdapterHooks as supported by Equinox
  • Installing the OTDT (and any OT/Equinox appl.)
    • using only existing p2 mechanisms
