title: Adobe PDF Forms - Text Field displays value only when clicked on it
body: <p>I have a PDF with forms defined in it.
  One field in the form is a multi line text field.</p>
  
  <p>The value in the text field is populated by a java program using Apache PDFBox.</p>
  
  <p>The issue is when the value is of around 5 to 6 lines, the text box displays the text automatically. But if it is more than 6 lines, the text box does not display the value. I had to specifically click on the text field to display the text. If I click outside the text box again, the text disappears.</p>
  
  <p>The text field is read only with Multi Line and Scrolling options enabled.</p>
  
  <p>Any ideas what is causing this weird issue?</p>
  
  <p>I have Adobe Acrobat Pro 11, Adobe Acrobat XI and Adobe Reader to view the files. All have the same issue.</p>
