[9] Review request for 7052708 Grammar error in EditorKit documentation

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-7052708
  webrev: http://cr.openjdk.java.net/~alexsch/7052708/webrev.00

  The typo in javadoc is fixed: using  "its setComponent method" and 
"its relationship" instead of "it's".

Thanks,
Alexandr.
