Description

java.lang.IllegalArgumentException: 2058 > -49861164
    java.util.Arrays.copyOfRange(Unknown Source)
    org.apache.pdfbox.pdmodel.font.PDType1Font.<init>(PDType1Font.java:223)
    org.apache.pdfbox.pdmodel.font.PDFontFactory.createFont(PDFontFactory.java:62)

This is because the /Fontfile /Length2 values are bogus. A negative /Length2 brings an IllegalArgumentException in Arrays.copyOfRange(), a huge value eats up memory because of padding. So I'm doing a repair for the /Length2 as well.
