Hi,

I am migrating a plugin which was earlier based on PDE to RAP environment.
The plugin was using a dependency: "org.eclipse.core.runtime.compatibility"
In RAP environment, this dependency was not there and i removed it. There were no compilation issues as well.
But now, when i am trying to access any class form that plugin i get following error. Any clue on what is missing here ? What is the usage of compatibility plugin ? Is there any alternative to fix it ?

Hi,
it's impossible to diagnose the problem only from the stack trace. Could
you post the result of osgi "ss" command (active plugins list)?

Here is the description of "|org.eclipse.core.runtime.compatibility|"
plugin:
"The |org.eclipse.core.runtime.compatibility |project exists for
backwards compatibility purposes only. It contains deprecated APIs.
(mostly dealing with the old plug-in registry)".
Maybe you are using some outdated/deprecated APIs??!!
