Hello,
I'm project manager of NetBeans IDE Plugin for RTC and now we want implement APT functionality in NetBeans IDE.
This is very big feature in RTC - planning possibility and for us this is one of main use cases to implement it.
And we have a huge problem with this module. I know that API for APT plugin isn't public but if in Eclipse it works so why the same code couldn't work in plain java application?
So we started from IterationPlanClient:

this.planClient = (IterationPlanClient) PlanningClientPlugin.getIterationPlanClient(repo)

And this code throws an exception:

SEVERE : !ExtensionRegistryReader.ErrorExtensionAdd!

And my question is what we should do before getting IterationPlanClient?
Maybe some configuration? Or maybe we needs some config files or other stuff from Eclipse? How to use it in external plain java application?
Because of this exception we cannot retrieve plan types, view modes and also, what is the most important thing, we cannot retrieve planed items for plan.

Could I please for any help?
