StanfordCoreNLP - Setting pipelineLanguage to German not working?

Question

I am using the pycorenlp client in order to talk to the Stanford CoreNLP Server. In my setup I am setting pipelineLanguage to german like this:

from pycorenlp import StanfordCoreNLP

nlp = StanfordCoreNLP('http://localhost:9000')

text = 'Das große Auto.'

output = nlp.annotate(text, properties={
  'annotators': 'tokenize,ssplit,pos,depparse,parse',
  'outputFormat': 'json',
  'pipelineLanguage': 'german'
  })

However, from the looks I'd say that it's not working:

output['sentences'][0]['tokens']

will return:

[{'after': ' ',
  'before': '',
  'characterOffsetBegin': 0,
  'characterOffsetEnd': 3,
  'index': 1,
  'originalText': 'Das',
  'pos': 'NN',
  'word': 'Das'},
 {'after': ' ',
  'before': ' ',
  'characterOffsetBegin': 4,
  'characterOffsetEnd': 9,
  'index': 2,
  'originalText': 'große',
  'pos': 'NN',
  'word': 'große'},
 {'after': '',
  'before': ' ',
  'characterOffsetBegin': 10,
  'characterOffsetEnd': 14,
  'index': 3,
  'originalText': 'Auto',
  'pos': 'NN',
  'word': 'Auto'},
 {'after': '',
  'before': '',
  'characterOffsetBegin': 14,
  'characterOffsetEnd': 15,
  'index': 4,
  'originalText': '.',
  'pos': '.',
  'word': '.'}]

This should be more like

     Das  große  Auto
POS:  DT     JJ    NN

It seems to me that setting 'pipelineLanguage': 'de' does not work for some reason.

I've executed

java -mx4g -cp "*" edu.stanford.nlp.pipeline.StanfordCoreNLPServer -port 9000 -timeout 15000

in order to start the server.

I am getting the following from the logger:

Apparently the server is loading the models for the English language - without warning me about that.

Alright, I just downloaded the models jar for German from the website and moved it into the directory where I extracted the server eg

~/Downloads/stanford-corenlp-full-2017-06-09 $

After re-running the server, the model was successfully loaded.
