I asked for Mark's and Joe's inputs on this in the linked JBS issue https://bugs.openjdk.org/browse/JDK-8233160. Mark has suggested that we keep this `java.vendor.url.bug` system property non-optional and also not to add any expectations of the value for this property to be a parsable URL.

Both of those inputs match with what is currently proposed in this PR. I'll go ahead and draft a CSR shortly.
