Remove the block regarding selection, you don't need it as far as I can see.
/*
                    ISelection iselection = window.getSelectionService().getSelection();
                    IStructuredSelection selection = (IStructuredSelection) iselection;
                    if (selection == null) {
                        log.error("null selection");
                        return;
                    }
*/

I selected a tab in Eclipse Edit window.

my code to get the selected open file project like this:

public static void getCurrentProject() {
        Display.getDefault().asyncExec(new Runnable() {
            @Override
            public void run() {
                IWorkbenchWindow  window = PlatformUI.getWorkbench().getActiveWorkbenchWindow();

                if (window != null) {
                    ISelection iselection = window.getSelectionService().getSelection();
                    IStructuredSelection selection = (IStructuredSelection) iselection;
                    if (selection == null) {
                        log.error("null selection");
                        return;
                    }

                    IWorkbenchPage activePage = window.getActivePage();

                    IEditorPart activeEditor = activePage.getActiveEditor();

                    if (activeEditor != null) {
                       IEditorInput input = activeEditor.getEditorInput();

                       project = input.getAdapter(IProject.class);
                       if (project == null) {
                          IResource resource = input.getAdapter(IResource.class);
                          if (resource != null) {
                             project = resource.getProject();
                          }
                       }
                    } else {
                        log.error("null activeEditor");
                    }
                } else {
                    log.error("null window");
                }
            }
        });
    }

and window variable is not null but selection  is null.  Is my understanding wrong?

project  is a class static member variable.

Thanks.
