Error generating PDF after latest Acrobat update

[aduncan_24018]

I have been successfully generating PDFs from Adobe Robohelp for several months now. Last week, Acrobat updated to the latest version, and now I'm receiving the following error generating a PDF. This is the same RH project I have successfully generated a PDF from in the past. 

I also updated to the latest Java version in case there was a mismatch.

Versions:

Adobe Robohelp: 2022.6.34

Adoboe Acrobat: 2025.001.20756

Java: Version 8 Update 461 (build 1.8.0_461-b11)

Command failed: java -jar -Djava.awt.headless=true -XX:+UseG1GC -XX:MaxGCPauseMillis=1000 "C:/Program Files/Adobe/Adobe RoboHelp/resources/data/pdf/pdf-publisher.jar" "C:/Users/AMYDUN~1/AppData/Local/Temp/RHTMP/PDF4F6x2s/config/mergedHTML.json" "C:/Users/Amy Duncan/Documents/My RoboHelp Projects/outputs/Caterpillar - 22475/CAT22475.pdf" [main] INFO com.adobe.guides.pdf.mapper.ConfigurationMapper - Patching remaining config properties Exception in thread "main" java.lang.StackOverflowError at java.lang.AbstractStringBuilder.append(Unknown Source) at java.lang.StringBuffer.append(Unknown Source) at com.realobjects.xml.core.model.dom.save.Printer$TextToken.append(l:657) at com.realobjects.xml.core.model.dom.save.Printer.string(l:258) at com.realobjects.xml.core.model.dom.save.DOMBaseSerializer.b(l:762) at com.realobjects.xml.core.model.dom.save.DOMBaseSerializer.serializeText(l:615) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.b(l:672) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.d(l:737) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.b(l:635) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.d(l:737) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.b(l:635) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.d(l:737) at com.realobjects.xml.core.model.dom.save.DOMTreeSerializer.b(l:635)

I solved the mystery, and it didn't have anything to do with the Acrobat update. We had inserted PDFs as iFrames into our TOC, and the PDF generator fails as a result. I removed those iFrames, and it works as expected. This would be helpful to add to the log, however. It could save others hours of troubleshooting time.

Thank you for posting the answer. The forum works better when people do that. 🙂
