Try this in case you are running the km200-binding which needs strong encryption support:
@ThomDietrich Can we integrate this step in the setup procedure ?
Zulu JVM - Setup strong encryption:
http://www.azul.com/products/zulu/zulu-cryptography-extension-kit/
Accept the license agreement, then download and install the strong encryption policies (use sudo!):
wget http://cdn.azul.com/zcek/bin/ZuluJCEPolicies.zip
unzip ZuluJCEPolicies.zip
cd ZuluJCEPolicies
cp *.jar /usr/lib/jvm/zulu-embedded-8-armhf/jre/lib/security
reboot
This worked for me, the error in the log is gone afterwards. I rebooted to make sure everthing is working fine after the file exchange.
