| ____ |
| RAP is multi user framework by its nature. Every user session is |
| associated with a display. In RAP, Display#getDefault() will not create |
| a new display when it's called from non-UI thread - read |
| Display#getDefault JavaDoc. When you execute a code in a background |
| thread, RAP needs to know for which UI session (display) it belongs. |
| That's why you have to provide the correct UISession/display from outside. |

| ____ |
| A menuitem with SWT.CASCADE without a submenu looks and behaves differently from SWT. |

| - The menuitem is clickable. |
| |
| RWT: |
| |
| - The menuitem has a right arrow. |
| - The menuitem is NOT clickable. |

| === CTabFolder.setSimple() is not allowed |
