Description

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.
