Ah! Got it! :-)
That bit of debug it spat out indicated a problem with what I was passing from
Lucee into the overlay() call.
It turns out that a regular Lucee/CFML struct defined with numeric keys are
actually strings! So it couldn't figure out what to do with the keys (structs
are Maps in the Java world).
What I've ended up doing is creating a LinkedHashMap (which is compatible with
the Map<Integer,String> type for overlay())
<cfset local.guide = createObject("java", "java.util.LinkedHashMap").init()>
And then using the put() method on the object with a cast Integer as the key
and a string (the overlay path) as the value:
<cfset local.guide.put(javaCast("integer", local.i+1), arguments.overlay_path)>
And lo and behold, the overlay() call no longer errors and I get what I wanted.
I couldn't be more delighted!
Thank you Tilman, for the verbose version and the help! Who knew Lucee was so
finicky! ;-)

Interesting!
That version throws an error:
class java.lang.String cannot be cast to class java.lang.Integer
(java.lang.String and java.lang.Integer are in module java.base of loader
'bootstrap')
at Overlay.java, line 132.
I wonder if there's something fundamentally problematic about data types in the
Lucee part and the non-verbose version just ignores it and throws its hands up
and says "no"?

Got it. Thanks Tilman!
Will let you know if I manage to figure out how to see the debug! 🙂

Hi,
Use this version:
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/3.0.6-SNAPSHOT/pdfbox-app-3.0.6-20250711.072333-59.jar
please tell when you've downloaded it so that revert these changes.
