When clicking on "+" to show a page from the file from 
https://github.com/mozilla/pdf.js/issues/9597 :
{code}
java.lang.NullPointerException: null
    org.apache.pdfbox.debugger.ui.PDFTreeCellRenderer.toTreePostfix(PDFTreeCellRenderer.java:214)
    org.apache.pdfbox.debugger.ui.PDFTreeCellRenderer.toTreeObject(PDFTreeCellRenderer.java:121)
    org.apache.pdfbox.debugger.ui.PDFTreeCellRenderer.getTreeCellRendererComponent(PDFTreeCellRenderer.java:77)
    java.security.AccessController.doPrivileged(Native Method)
    java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:80)
    java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:90)
    java.security.AccessController.doPrivileged(Native Method)
    java.security.ProtectionDomain$JavaSecurityAccessImpl.doIntersectionPrivilege(ProtectionDomain.java:80)
{code}
The cause is a broken PDF with a /Subtype that is not a name. I'll fix that and do the same for /Type.
