/*

Below are some notes about changes in SortingFocusTraversalPolicy behaviour.

container(root) [...]           - focus traversal cycle with the <container> as the root.
container(provider) [...]       - focus traversal cycle with the <container> as the provider.
container(..)(focusable) [...]  - <container> is implicitly set focusable.
comp[unfocusable]               - <comp> is set unfocusable.


1. frame [ container(root)(focusable) [...] ]

- getComponentAfter(<frame>, <container>) returns <container>.

  If <container> is the default component to focus in its own cycle.  * NO CHANGE *


3. frame [ comp1 container(root)(focusable) [ comp2 ] comp3 ]

- getComponentBefore(<frame>, <comp3>) returns <comp2>.                                 ** BEHAVIOUR CHANGE **

  Previously <container> would be returned. This was a bug as it
  wasn't according to the spec.

- getComponentBefore(<container>, <comp2>) returns <container>.     * NO CHANGE *

- getComponentBefore(<frame>, <container>) returns <comp1>.         * NO CHANGE *

- getComponentBefore(<container>, <container>) returns <comp2>.     * NO CHANGE *


4. frame [ container(provider) [...] comp ]

- getComponentAfter(<frame>, <container>) returns <container>'s default.                ** BEHAVIOUR CHANGE. SPEC ADDITION **

  Previously <comp> would be returned. Not specified in the spec.

- getComponentBefore(<frame>, <comp>) returns <container>'s last.                       ** SPEC CHANGE **

  The spec says (incorrectly) that default should be returned.


5. frame [ container(provider)(focusable) [...] comp2 ]

- getComponentBefore(<frame>, <comp2>) returns <container>'s last.                      ** BEHAVIOUR CHANGE. SPEC ADDITION **

  Previously <container> would be returned. Not specified in the spec.


6. frame [ comp1 container(root) [...] comp2 ]

- getComponentAfter(<frame>, <comp1>) returns <container>'s default.                    ** BEHAVIOUR CHANGE. SPEC ADDITION **

  Previously <comp2> would be returned. It's just the fix for 6240842.
  Not specified in the spec.


7. frame [ comp1 container(root) [...] comp2(unfocusable) comp3 ]

- getComponentBefore(<frame>, <comp3>) returns <container>'s default.                   ** BEHAVIOUR CHANGE **

  Previously <comp1> would be returned. This was a bug, because
  in case if <comp2> is focusable getComponentBefore(<frame>, <comp2>) would
  return <container>'s default.
