The report is as follows:
102383 Dereference null return value If the function actually returns a null value, a NullPointerException will be thrown. In org.bson.codecs.pojo.PojoBuilderHelper.configureClassModelBuilder(org.bson.codecs.pojo.ClassModelBuilder, java.lang.Class): Return value of function which returns null is dereferenced without checking (CWE-476)
It's not immediately obvious whether an NPE can happen in practice, but it should be investigated and the Coverity issue updated appropriately.
