             Summary: PDFDebugger Text View for Streams hides errors
                 Key: PDFBOX-4964
                 URL: https://issues.apache.org/jira/browse/PDFBOX-4964
             Project: PDFBox
          Issue Type: Bug
          Components: Utilities
    Affects Versions: 3.0.0 PDFBox
         Environment: Win10
            Reporter: Michael Klink
         Attachments: 2-30-SL-manual-DE.pdf, 2-30-SL-manual-DE.pdf-6-2-Hex.png,

In the context of [this stack overflow 
question|https://stackoverflow.com/q/64013884/1729265] I used the PDF Debugger 
to inspect the second page content stream of page 6 of the document provided as 
example, 
[2-30-SL-manual-DE.pdf|http://www.autosfera.lt/images/Manuals/Nussbaum/2-30-SL-manual-DE.pdf],
 also attached to this issue.

The problem that question was about is caused by an invalid literal (neither 
string nor number) in some *TJ* instruction array argument. This literal indeed 
was visible in the hex view of the PDF debugger:

!2-30-SL-manual-DE.pdf-6-2-Hex.png!

(See the "Tw" literals in the *TJ* arrays.)

But in the text view it was hidden:
