Perhaps this is a stupid question, and someone please enlighten me - but would not the vast majority of JVM deployments be on either CentOS or Debian-derived base images with good support for an OpenJDK package?

I thought that the main differences between OpenJDK and Oracle java was the nicer font rendering and some Swing-ish stuff, is there a good comparison as to why people even use the Oracle Java?
