I have avoided the NPE until we have a better solution. I haven't been able to
reproduce it in 2.0, however I found another occurrence in 3.0 and the trunk.

> Posted by Haoran Yan on the users mailing list:
> NullPointerException (NPE) in COSDocument. Specifically, when a

> at line 219 of COSDocument.java.
> Reproduce:
> Run the following test case:
> {code:java}
> public class TestClass {
> @Test
> public void test() {
> COSDocument document = new COSDocument();
> Map<COSObjectKey, Long> xrefTable = new HashMap<>();
> xrefTable.put(null, 10L);
> document.addXRefTable(xrefTable);
> document.getLinearizedDictionary();
> }
> }
> {code}
