O arquivo cacerts está ausente no ubuntu 15.10 e no openjdk-8-jdk?
Acabei de instalar o Ubuntu 15.10 e seu openjdk-8-jdk (pelo apt-get).
Agora estou sentindo falta do arquivo cacerts.
Há um link no local usual:
ls -l /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts
lrwxrwxrwx 1 root root 27 Oct 22 01:47 /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/cacerts -> /etc/ssl/certs/java/cacerts
mas nada em / etc / ssl / certs / java / cacerts:
stat /etc/ssl/certs/java/cacerts
stat: cannot stat ‘/etc/ssl/certs/java/cacerts’: No such file or directory
