----------------------------------------------------------------
[~lehmi] I am using PDFBox to create one PDF document by merging multiple PDFs
documents. I have tried the same on PDFBox 2.0.24 as well.
PDFBox is internally using org.apache.commons.logging library. And Yep
exception seems due to commons.logging lib which is propagating it to PDFBox.
