I recently updated my Eclipse from 3.5 to 3.6 and have noticed that the UI behavior of the Job API has changed
Whenever I launch multiple jobs in my RCP application running under 3.6, multiple job popups appear that represent the exact same data. 

Reproducible: Always

Steps to Reproduce:
1. Create a sample RCP Application
2. Bind the following code with an action and a toolbar button:
        Job job = new Job("long running action") {
            protected org.eclipse.core.runtime.IStatus run(IProgressMonitor monitor) {

                // Generator.this.mainView.getButtonGenerateConstraints().setEnabled(false);
                monitor.beginTask("Long running action", 100);
                for (int i = 0; i < 10; i++) {
                    if (monitor.isCanceled()) {
                        // Generator.this.mainView.getButtonGenerateConstraints().setEnabled(true);
                        return Status.CANCEL_STATUS;
                    }
                    monitor.subTask("working on step " + i);
                    monitor.worked(10);
                    MyAction.this.sleep(1000);
                }
                monitor.done();
                // Generator.this.mainView.getButtonGenerateConstraints().setEnabled(true);
                return Status.OK_STATUS;
            }
        };
        job.setUser(true);
        job.schedule();

3. Press multiple times on the button. Many repetitive popups of the same job(s) appear, and they contain the exact same data
