# populate Java's certificate store (solution from https://stackoverflow.com/questions/6784463/error-trustanchors-parameter-must-be-non-empty/25188331#25188331)
## 1. Save an empty JKS file with the default 'changeit' password for Java cacerts.
##    Use 'printf' instead of 'echo' for Dockerfile RUN compatibility.
/usr/bin/printf '\xfe\xed\xfe\xed\x00\x00\x00\x02\x00\x00\x00\x00\xe2\x68\x6e\x45\xfb\x43\xdf\xa4\xd9\x92\xdd\x41\xce\xb6\xb2\x1c\x63\x30\xd7\x92' > /etc/ssl/certs/java/cacerts

## 2. Re-add all the CA certs into the previously empty file.
/var/lib/dpkg/info/ca-certificates-java.postinst configure

# (Above solution fix this) need to do this to fix broken certificate problem ("This Jenkins instance appears to be offline.")
# sudo sed -i 's/https/http/' /var/lib/jenkins/hudson.model.UpdateCenter.xml
