The AbstractUIPlugin[2] states that the deprecated method startup(), which start() is meant to replace cannot assume that it is run on the UI thread. This may be a bit pedantic: the specification for start() doesn't mention anything about the UI thread- is it still the case that we can't assume the start() method is run on the UI thread?<br class=""><br class="">If it is the case that the start method can't assume that it's run on the UI thread, I will need to change some of the code to ensure that this assumption is not made.<br class=""><br class="">The offending line attempts to register a selection listener. Here it is:<br class="">((ISelectionService) getWorkbench().getActiveWorkbenchWindow().getService(ISelectionService.class)).addSelectionListener(this.contextActivatingSelectionListener);<br class=""><br class="">Do you know of any other ways to register this listener?<br class=""><br class="">Your help is greatly appreciated.<br class=""><br class="">Thank you,<br class="">Ian<br class=""><br class="">[1] - <a href="https://github.com/eclipse/buildship/" class="">https://github.com/eclipse/buildship/</a><br class="">[2] - <a href="http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fui%2Fplugin%2FAbstractUIPlugin.html" class="">http://help.eclipse.org/mars/index.jsp?topic=%2Forg.eclipse.platform.doc.isv%2Freference%2Fapi%2Forg%2Feclipse%2Fui%2Fplugin%2FAbstractUIPlugin.html</a><br class=""></div></blockquote></div><br class=""></div></body></html>
