NullPointerExcception with "logger" object in "RTEPairsPreProcessor" class, in BIUTEE

[hoangyenan]

Hi all,

When testing the BIUTEE, the new release code,according to the instructions at webpage (https://github.com/hltfbk/Excitement-Open-Platform/wiki/BIUTEE#wiki-interface_eop), I tried to use the command:

mvn -f /home/daniel-vo/Desktop/EOP-Testing-Project/EOP-1.0.2/biutee/pom.xml exec:java -Dexec.mainClass=eu.excitementproject.eop.biutee.rteflow.systems.excitement.BiuteeMain -Dexec.args="biutee.xml lap_train"

to preprocess the training data, however, I always get NullPointerException error and I found that in the class eu.excitementproject.eop.biutee.rteflow.systems.rtepairs.RTEPairsPreProcessor, at the method preprocess(), the logger.info() always returns NullPointerexception error.

I find in this class and realize that the object "logger" was initiated in the main function, and somehow, when we run the command above for preprocessing training data, the "logger" object was not initiated and that's why it always returns NullPointerException error in any method carries this "logger" object.

I tested by putting comments at any method "logger.info()" and no more NullPointerException error returned.
