Hi! I want to merge several Documents to a single PDF-Document. The Docs I want to merge were previously splitted from a bigger document. During my loop I received the following Exception
java.lang.NullPointerException: Cannot invoke "org.apache.pdfbox.pdmodel.common.COSObjectable.getCOSObject()" because the return value of "java.util.Map$Entry.getValue()" is null at org.apache.pdfbox.multipdf.PDFMergerUtility.appendDocument(PDFMergerUtility.java:878) During debugging I can see that a couple of values in the srcNumberTreeAsMap were null. I am using the latest release 3.0.4. and I could not found any JIRA-Issue, maybe it is a new one. Unfortunately I can not provide the Docs I want to merge, because the content is confidential and with other docs it works perfect. Do you have an idea how I can analyse the issue? Thx, in advance Olli
