Description

When receiving a PDF document as a byte array, users need to convert the data manually to a PDF document. For instance, consider a route like:

    from("direct:consumePDF")
                .process(this::convertBytesToPDFFile) // -> this is needed to convert
                .pipeline()
                    .to("pdf:extractText")
                    .process(...);

Then, the convertBytesToPDFFile should contain something like:

final byte[] body = e.getMessage().getBody(byte[].class);

PDDocument document = Loader.loadPDF(body);

This makes designing routes that consume PDFs harder.
