This is a bug in the specification, not the implementation.  As I just
wrote in a comment on 8197927:

JEP 322 expresses the intended behavior: If `--with-vendor-version` is
not specified at build time then the `java.vendor.version` property has
no value.  (That's different from the empty string, which is a value.)
The bug is in the specification, which should be revised so as not to
require that this property have a value.  Fixing the spec is not
critical for 10; I suggest downgrading 8197927 to P2 and targeting 11.
