    Problem exporting to PDF after migrating to Java11

    EDIT: found the issue, fonts and fontconfig is apparently not included in Oracle (and other) JVMs as of Java 11... Is there some standard, easy-ish way to fix this?

    Hi, I got an exception in SmartGWT after trying out a pdf export running 11 rather than 8.

    It works when I run on my machine with Zulu 11, but in my test environment where I only have access to the 11.0.9+7-LTS from Oracle, I get the below error.
    Not sure how this can work with Zulu but not Oracle, thought I'd ping you since you might had seen it before?

    Cheers

    We've never seen this before, but what's basically going on is that the iText library (our PDF renderer) is trying to load a font and it's either not present or not allowed to be accessed.

    Since iText follows CSS font fallbacks, assuming you've left the default font fallbacks from our skins in place, this means iText is probably trying to load something basic that should always be there (possibly "Arial" or even any sans-serif).

    If that's failed, it likely means that fonts are completely inaccessible in this JDK deployment, perhaps because Oracle tried to ship a truly stripped-down JDK for servers, and assumed AWT font rendering wouldn't be needed. But it is, for a PDF export.

    We ran your problem by ChatGPT, and it suggested various files and configurations to look at (the log is just one question and reply):
