Fix Java 'trustAnchors parameter must be non-empty' error on Alpine Linux

The easiest way to fix the java error the trustAnchors parameter must be non-empty‘on Alpine Linux, is to copy the /etc/ssl/certs/java/cacerts file form another distro -eg. Arch Linux- to /usr/lib/jvm/java-1.7-openjdk/jre/lib/security/

That’s all :)
