Reviews run for a minimum of one week. The outcome of the review is decided on this date. This is the last day to make comments or ask questions about this review.
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
- No incompatibilities to previous releases
The project leadership certifies that the APIs in this release are "Eclipse Quality".
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.
No known security issues
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
Continued improvements, and adoption of upstream improvements.
Nothing has been deprecated.
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
- Interaction in Bugzilla
- Activity on the Object Teams newsgroup
- Object Teams blog is integrated on planet.eclipse.org and features Object Teams as well as JDT/Core work
Tight integration with the JDT team
- Some bugs in JDT found during work on Object Teams
- All improvements in the JDT are promptly adopted in Object Teams
Object Teams was/is featured in these presentations:
- Redefining Modularity with Object Teams at Eclipse Day Krakow 2012
- Redefining Modularity and Reuse in Variants—All with Object Teams at JavaOne 2012
- New Refactorings in the Object Teams Development Tooling at Eclipse Demo Camp Kepler, Berlin.
- Object Teams technology was used by one Team during the 2. Eclispe Plug-in Fest Dresden.
