jpdfbookmarks is a Java tool for adding and editing bookmarks (outlines) in PDF files, but none of the candidate sources describes it, so the products below are general PDF libraries that can work with PDF bookmarks. iText is a Java and .NET PDF SDK that can create and manipulate PDF documents 6, and MuPDF is a library for managing PDF documents that covers editing and merging 1; neither source explicitly names bookmark editing.
A question back: Do you need to add bookmarks to PDFs from a Java project, and is jpdfbookmarks the Java tool you want, or are you looking for a different platform (e.g. .NET or a command-line tool)?
