Wolfgang Glas commented on PDFBOX-976:
--------------------------------------

Hi all,

  This issue is a real blocker, which prevents a fair amount of users from using pdfbox-1.5.0.

  Please consider releasing a pdfbox-1.5.1 version in order to provide these sers with a  possibility to use pdfbox-1.5 features.

    TIA, Wolfgang

> Using PDFont.getFontWidth() on a TrueType font fails with ClassCastException in PDFBox 1.5.0:
> Exception in thread "main" java.lang.ClassCastException: java.lang.Integer cannot be cast to java.lang.Float
> 	at org.apache.pdfbox.pdmodel.font.PDFont.getFontWidth(PDFont.java:786)
> 	at org.apache.pdfbox.pdmodel.font.PDSimpleFont.getFontWidth(PDSimpleFont.java:191)
> 	at org.apache.pdfbox.pdmodel.font.PDFont.getStringWidth(PDFont.java:283)
> 	at ...
> This is due to PDTrueTypeFont.loadDescriptorDictionary(...) loading a non-generic List of Integer instances (lines 342-355) and then calling setWidths() with that list in line 356. But the list has been declared as List<Float>. PDFont.getFontWidth(int) then fails in line 786 with that the exception.
