Incidentally, using JAVA_PREFERRED_PORTS as such will correctly use
openjdk11 only if the port allows it in its version list, eg:
    USE_JAVA=8+
or
    USE_JAVA=yes
    JAVA_VERSION=8+

If a port mandates the use of a specific version with:
    USE_JAVA=8
or
    USE_JAVA=yes
    JAVA_VERSION=8
The port-system will correctly ignore JAVA_PREFERRED_PORTS and use
openjdk8 instead.

Cheers.
