JTextComponent.setFocusAccelerator() spec does not state that focus accelerator is L&F dependent

The JTextComponent.setFocusAccelerator() spec at
http://download.java.net/jdk8/docs/api/javax/swing/text/JTextComponent.html
states the focus accelerator is the combination of the ALT key and an uppercase character.

However, the focus accelerator appears to be L&F dependent.
For example, on Mac:
Metal L&F: ALT+[uppercase character]
Aqua L&F: CTRL+ALT+[uppercase character]

The spec should be updated to state this is L&F dependent behavior.
