Hello Alan,

> I just wonder if it should be optional (like java.vendor.version),

I am unsure too. I decided to go with non-optional for now to match with the `java.vendor.url` system property which too is non-optional.



> and whether the value must be parsable as a URL. The question on whether the value can be interpreted as a URL applies to the exiting java.vendor.url property too.

My understanding is that these URLs are there mainly to be visible in log files or other such places and not for programatic parsing/construction. Especially for `java.vendor.url.bug`, I think it would be a rare thing to have it being parsed into URL programatically. So it may not be useful to add the restriction that this must be a parsable URL.
