Failed to create INI/HIA requests (Message not EBICS-conformant)

[Vinylrider]

I tried to create INI/HIA requests after creating EBICS database with command (mvn exec:java -Dexec.mainClass=org.kopi.ebics.client.EbicsClient -Dexec.args="--create") but the software says:

mvn exec:java -Dexec.mainClass=org.kopi.ebics.client.EbicsClient -Dexec.args="--ini --hia"

Here is my EBICS.txt configuration file :

password=xxxxxxxxx
userId=yyyyyyyy
partnerId=zzzzzzzz
hostId=70010080
bank.url=https://ebanking.postbank.de/tristan/ebics
bank.name=POSTBANK
user.name=Testname
user.email=testname@test.com
user.country=Germany
user.org=Testorg
languageCode=de
countryCode=DE
productName=EBICS Java Kernel 1.0

Is there anything I can do or is the software simply not compatible with german POSTBANK EBICS implementation ?
