title: Eclipse shows error for MissingCellPolicy
body: <p>I am using Apache POI to read data from Excel files. I have some blank/null cells in my Excel which I want to handle using <code>MissingCellPolicy.RETURN_NULL_AND_BLANK</code>. However, Eclipse underlines <code>RETURN_NULL_AND_BLANK</code> when I hover the mouse over it and I get a pop-up saying <i>RETURN_NULL_AND_BLANK cannot be resolved or is not a field</i></p>
  
  <p>I have imported the Row.MissingCellPolicy class. Can anyone point out what needs to be done?</p>
