ssplit.eolonly rises NullPointerException at edu.stanford.nlp.pipeline.NERCombinerAnnotato

[verosol]

So, basically we have an already tokenised corpus with golden sentence segmentation, which we want to preserve. Evidently, we found this parameters :
tokenize.whitespace = true
ssplit.eolonly = true

They work alright together with tokenize,ssplit,pos,lemma and parses, but it we want to pass all the annotators needed for the coreference resolution
annotators = tokenize,ssplit,pos,lemma,ner,parse,coref

it gives error Nullpointer exception specifically on NER annotation part.
