Hi,
When I run "java -jar target/jpmml-lightgbm-executable-1.3-SNAPSHOT.jar --lgbm-input model.txt --pmml-output lightgbm.pmml", there was an error with the following information:

Exception in thread "main" java.lang.NullPointerException
	at org.jpmml.lightgbm.LightGBMUtil.parseStringArray(LightGBMUtil.java:100)
	at org.jpmml.lightgbm.LightGBMUtil.parseIntArray(LightGBMUtil.java:111)
	at org.jpmml.lightgbm.Section.getIntArray(Section.java:62)

	at org.jpmml.lightgbm.Main.run(Main.java:141)
	at org.jpmml.lightgbm.Main.main(Main.java:134)
