[eclipse-dev] Re: [equinox-dev] Update to Jetty and Servlet API in the M

[Simon Kaegi <Simon_Kaegi@xxxxxxxxxx>]

The version 2 bundle already existed and was part of the Ganymede Equinox SDK.

There were originally some build issues, and concerns over tighter integration with Jetty some folk were planning on doing with fragments that led us to bump the version.
In retrospect a 1.x bundle version would have been better and indeed we briefly discussed this on the equinox call but quickly concluded that the risks associated with rolling back the version of an existing released bundle would cause even more confusion.

Yes you're right.
The bundle-version on org.eclipse.equinox.http.jetty is bumped to "2.0" so to high-light Alex's point/concern...
There is the possibility of breakage if a team used a version restricted Require-Bundle with major version semantics like:
Require-Bundle: org.eclipse.equinox.http.jetty; bundle-version="[1.1,2.0)
The Export-Package is still using "1.1" so Import-Package users should be fine.

As a result of this change it is important for teams that are using the server-side bundles to verify as this change could cause problems. This is why the original email was sent and is a pre-step for an entry in the 3.4 to 3.5 migration guide.
In most cases all should be well since the actual binary API has not changed although the bundle metadata has.

I thought that an API compatible change was only meant to increment  
the minor version number, rather than the major number?
