StanfordCoreNLP - Setting pipelineLanguage to German not working? - stanford-nlp

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 e.g.
~/Downloads/stanford-corenlp-full-2017-06-09 $
After re-running the server, the model was successfully loaded.
