This is an umbrella CR for spec change. It collects problems raised in CRs
6240842, 6463097 and 6463516. These problems are as follows:

1. There is a focus traversal cycle in which a component is followed by a
   container and the container itself is a focus cycle root. In such a case
   if a forward traversal begins from the component, then the focus will jump over
   the container whereas down-cycle traversal (into the container's cycle) is
   expected. The problem concerns only the Swing policy.
 
2. A container, that was made focusable explicitly and at the same time is a
   focus traversal policy provider doesn't allow to traverse its content in
   forward traversing. The focus goes to the container and then to the next
   component in the cycle, not getting inside the container. The problem is
   common both for Swing and AWT.
   Besides, during the normal backward traversal, that container also doesn't
   allow the focus to get in as well.
 
3. In accordance with the focus spec if the
   FocusTraversalPolicy.getLastComponent method is called,
   and an obtained component is a focus traversal policy provider, then its
   default component is returned. The statement is wrong. The returned component
   is the last.
   The same is for FocusTraversalPolicy.getComponentBefore. If an obtained
   component is a focus traversal policy provider, then its last component
   should be returned (not the default).

The correct behaviour should be described in the focus spec.

Bug Description:
Likely related to: 6240842, 6450939, 6463545, 4788402, 4815672

CTRL-TAB will not transfer focus from the "two" text field. CTRL-SHIFT-TAB will transfer the focus. Also, in my app which has many more components, the CTRL-TAB really hammers the CPU...yet still results in nothing.


Steps to Reproduce (be specific):
Run project
