3.1

- create a "hello world" headless app (just writing to console), but where the
plug-in class extends AbstractUIPlugin
- the following exceptions occur:

java.lang.NullPointerException

Comment 1 Nick Edgar

This occurs because the workbench has not been run, but when
PlatformUI.isWorkbenchRunning() is called, it tries to resolve class Workbench
and others, which fails because the runtime has already been shut down.

Both the runtime logging and PlatformUI.isWorkbenchRunning() should be resilient
to this.

Reassigning bugs in component areas that are changing ownership.

Lowering priority in absence of product fail case

Prakash is now responsible for watching bugs in the [RCP] component area.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
