Description

org.apache.pdfbox.io.RandomAccessReadBufferedFile creates a new instance of {{org.apache.pdfbox.io.RandomAccessReadBufferedFile}} which opens a new file using the underlying file every time when creating a new view. The view of a COSStream isn't most likely closed until the entire pdf is closed. In the end there are as many open files as created COSStreams until the pdf is closed.
