Re: [cross-project-issues-dev] Bug 456909 - Implementing Early Startup IStartup causes org.eclipse.core.runtime.CoreException


so far this issue was reported in two platform error reports by ~500 users each [1,2]. I added a comment to these problem reports which informs users that the early startup extensions they use, stopped working properly in Eclipse Mars and that they should inform their plugin providers about this to allow them taking care of this in their code.

At least there is an (indirect but focused) way informing 3rd party plugin providers about this breaking change before Eclipse Mars is released.

As such, instances where compatibility will be broken, should be announced at the highest volume possible and with much repetition. In this case, the particular extension point usage pattern was apparently deprecated in Eclipse 4.2 before being removed in 4.5. It would have been good to add a deprecation warning to the error log starting in 4.2 in order to ensure that the affected plugin maintainers notice that they need to take action while there is still plenty of time to plan for this. The final removal should have also been announced on cross-project.

> Plugins that have an IStartup extension and worked fine on 4.4 are causing exceptions to be logged when used on 4.5 milestones. This appears to be an API behavior regression. The bug was filed in January and the platform team has yet to comment on it…
