The JavaDoc of Cursor.handle:
the handle to the OS cursor resource (Warning: This field is platform 
dependent)
IMPORTANT: This field is not part of the SWT public API.

There are several fields/methods that are accessible but not part of the 
public SWT API. This is, because they need to access those from other 
SWT packages. Not nice, but at least in the JavaDoc its documented.
