Bug 34169 Add JUnit TestSuite blocks
In RC2 I was able to add a new JUnit test suite using the wizard. After 2 or 3 calls to wizard it stopped working. The "Next" button trigers some activity (mouse pointer changes) but does not advance to the next screen. The same workspace works fine with RC1 after this problem with RC2.
org.eclipse.jdt.junit/src/org/eclipse/jdt/internal/junit/wizards/JUnitWizard.java
protected boolean finishPage(IRunnableWithProgress runnable) {
		IRunnableWithProgress op= new WorkspaceModifyDelegatingOperation(runnable);
		try {
			getContainer().run(false, true, op);
		} catch (InvocationTargetException e) {
			Shell shell= getShell();
			String title= WizardMessages.getString("NewJUnitWizard.op_error.title"); 
			String message= WizardMessages.getString("NewJUnitWizard.op_error.message"); 
			ExceptionHandler.handle(e, shell, title, message);
			return false;
		} catch  (InterruptedException e) {
			return false;
		}
		return true;
	}
	protected void openResource(final IResource resource) {
		if (resource.getType() == IResource.FILE) {
			final IWorkbenchPage activePage= JUnitPlugin.getDefault().getActivePage();
			if (activePage != null) {
				final Display display= getShell().getDisplay();
				if (display != null) {
					display.asyncExec(new Runnable() {
						public void run() {
							try {
								activePage.openEditor((IFile)resource);
							} catch (PartInitException e) {
								JUnitPlugin.log(e);
							}
						}
					});
