> The user in the attached SO question noticed that the comb adjustment needed 
> a factor of 2 to work correctly. A look at the font shows UnitsPerEm = 2048.
> Sample code:
> {code:java}
> doc.getDocumentCatalog().getAcroForm().getField("field1").setValue("WWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWWW");
> doc.getDocumentCatalog().getAcroForm().getField("field2").setValue("MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM");
> {code}
>  !screenshot-1.png!
