According to the java spec regarding white space chars, if a char is a unicode space char but is not a non-break space then it is the java white space.

The test was failed with \u202f and \u2007 on build1.4.0beta-b44. Character.isWhitespace() returns true for them but they are non-break space. They are not java white space.
   
1.4.0beta-b44 was tested on win98 and 2 cases were failed.
