Bug 456909 - Implementing Early        Startup
IStartup causes org.eclipse.core.runtime.CoreException

FWIW,

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.

backwards compatibility. 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.

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…
