A little bit of googling suggests this is a problem with the headless version of OpenJDK used by Docker, which doesn't expect AWT/fonts to be needed. There are a couple...

OK, but I think we've established the cause of the problem: POI requires the AWT font classes which appear to be missing from the headless OpenJDK. Perhaps Ortus can address...

I'm afraid I can't tell you exactly which classes would need to be added. The library does call various AWT classes/packages explicitly but the NPE you've seen seems to be...

Yes this library, that what I meant. It relies on POI for almost everything. Annoying that it's only those two features. I totally agree we ideally want to identify just...

Strange, the `requiresJavaLoader` variable should be set when you instantiate `Spreadsheet.cfc`. Can you post the code you are using to do that? Can you also try running this method and...

What does your calling code look like?

Not sure I understand why you're using the local scope in that way. `local` is a built in scope within a function and doesn't need to be defined. You also...

I've tried replicating your dummy "local scope" in a template and it doesn't seem to affect things so we can rule that out. But I can't replicate the NPE unfortunately...

Those versions should be fine. Sorry am at a bit of a loss...

Yes, but I've tested your code with the `sheetName="Sheet1"` argument and it works fine for me (and many other people are using the library without issue). It must be something...
