How to handle LemmatizerTrainer 'UTFDataFormatException: encoded string too long'?

Question

I am using Opennlp to train a model for lemmatization of german words. Therefore I use the opennlp cli and the training set of UD_German-HDT which can be downloaded here

The training itself works fine (just need a little bit of ram) but the cli fails to write the model because of an UTFDataFormatException: encoded string too long exception.

The cli command I am using: opennlp LemmatizerTrainerME.conllu -params params.txt -lang de -model de-lemmatizer.bin -data UD_German-HDT/de_hdt-ud-train.conllu -encoding UTF-8

Stacktrace:

Has somebody encountered this problem and has a solution?
