Moving to PDFBox 2.0 is also on our roadmap. But the text extraction API in 2.0 has changed a lot too, so porting our engine would require quite a bit of effort.
Friendly reminder: we're an MIT-licensed open source project, and we're always open to contributions!
We use JPedal for rendering pages as images. For parsing, we use Apache PDFBox. In the near future, we plan to render the PDFs client side with Mozilla's PDF.js
