This in a native quarkus application using version 3.8.2. It's running in AWS as lambda using the latest runtime. I am using Java 21!. I think the latest runtime in AWS does not support fonts anymore.

I will try to set system prop: org.apache.poi.ss.ignoreMissingFontSystem

• see https://poi.apache.org/components/configuration.html

If this prop works can this also be added as configuration option for quarkus-poi?

[argenstijn]

It works in Amazon linux 2 but not when you use Amazone Linix 2023 as lambda provider

[argenstijn]

Setting org.apache.poi.ss.ignoreMissingFontSystem does not work in my situation!

Interesting:

Quarkus or quarkus-awt is now throwing a RuntimeException. But in the code of apache

@Internal
    public static float getDefaultCharWidthAsFloat(final Workbook wb) {
        Font defaultFont = wb.getFontAt( 0);

        AttributedString str = new AttributedString(String.valueOf(defaultChar));
        copyAttributes(defaultFont, str, 0, 1);
        try {
            TextLayout layout = new TextLayout(str.getIterator(), fontRenderContext);
            return layout.getAdvance();
        } catch (Throwable t) {
            // ignore exception and return a default char width if
            // the ignore-feature is enabled and the exception indicates that
            // the underlying font system is not available
            if (ignoreMissingFontSystem && (
                    // the three types of exception usually indicate here that the font
                    // system is not fully installed, i.e. system libraries missing or
                    // some JDK classes cannot be loaded
                    t instanceof UnsatisfiedLinkError ||
                    t instanceof NoClassDefFoundError ||
                    t instanceof InternalError  ||
                    // other fatal exceptions will always be rethrown
                    !ExceptionUtil.isFatal(t))) {
                return DEFAULT_CHAR_WIDTH;
            }

            throw t;
        }
    }

So the property does not work because awt/quarkus throws a runtime exception. Do you also agree with this?

See #95

I updated the Native build instructions for how to include .so files in the native build. Will close for now.
