Hi,

RTFM:
http://help.eclipse.org/help32/index.jsp?topic=/org.eclipse.jdt.doc.user/reference/preferences/java/compiler/ref-preferences-errors-warnings.htm


When enabled, the compiler will issue an error or a warning whenever it
encounters a field access which is not qualified (eg. misses a 'this').

=> change "x" to "this.x".
