You can also pass a wildcard expression, avoiding hardcoding several files,
maybe like this:

EnvironmentFile=-/etc/java-runtime.d/*
EnvironmentFile=-/etc/java-runtime

Needs testing, but could allow the user to set a default runtime via symlink.

Alternatively, just EnvironmentFile=/etc/java-runtime and create this symlink
at post_install of every java-runtime, if it doesn't exist already.
To be tidy, post_remove then deletes the file if java-runtime.d
doesn't exist anymore.
