To elaborate, Eclipse has a strong separation between Core vs UI.
The MI plugin including any of the *.core plugins may not be run within the context
of the UI thread.  So to do what you want, you need to wrap the code
in a runnable, something like:

Runnable uiTask = new Runnable() {
   // some code.
   // InputDialog dialog = new InputDialog(shell, "Label Dialog:", "Enter
..
}
PlatformUI.getWorkbench().getDisplay().asynExec(uiTask);

If not you will have funky errors like:
"Illegal access to SWT..."
NPE
etc ...

But ... it's not the good approach 8-), see mikhail's comments below
on a better approach.
