Modify Eclipse UI from plugin

I'm building a plugin for eclipse which performs some static analysis on the projects currently found in the workspace. I have an implementation of AbstractHandler, the execute method is called when my button is pressed in Eclipse.

Once my analysis has been completed, for now, I want a new text window to open in Eclipse with the output of the analysis.

I've followed the vogella tutorial here http://www.vogella.com/tutorials/EclipseJobs/article.html#eclipsejobs_uisynchronize which explains that I need to inject a UISynchronizer object (or rather, eclipse will inject it for me) and call the asynch(Runnable) method from the handler. However, when I import UISynchronizer, Eclipse gives the warning:

Discouraged access: The type UISynchronizer is not accessible due to restriction on required library /Applications/eclipse/plugins/org.eclipse.ui.workbench_3.105.2.v20140211-1711.jar

Is this to discourage the average user from using the UISynchronizer class? Or should I be using a different method to update the UI from my handler?

UISynchronizer is for a Eclipse e4 style application, since you are using AbstractHandler you must be writing an Eclipse 3.x style plugin so it is not an appropriate thing to use.

Instead use Display.asyncExec:

Display.getDefault().asyncExec(runnable);

This is actually what UISynchronizer uses internally.

For the record the 'Discouraged access' warning is because the UISynchronizer interface has not yet been finalized and might change. For an e4 application this warning can be ignored.

Update:

Checking again the e4 class is UISynchronize not UISynchronizer which is an internal class and should not be used at all.
