Apache PDFBox and CodenameOne Desktop app

I have a CodenameOne project which is mostly done, I need to integrate the desktop version with PDFBox. I am trying to open a document and render pages to images which I display in the application.

I get the following error:

I'm at a total loss. I have checked that the libraries are included, it manages to render one or two of the pages, but no more than that. I've even checked that the function does exist, and it does.

The problem appears to be with the way Codename One does the build process. By including the jar files in the result project and making them load higher in the jar load order than the app.jar file, the issue is resolved.

Did you place the jars of the PDF box API under the native/javase folder? If not the jar won't be sent to the build server and won't be packaged as part of the application.
