Alan - I reviewed the new webrev and looks good. To follow up the comment about invalid profile attribute value:

L820: An empty "Profile" attribute is invalidand Version.supportsProfile returns false if requiredProfile parameter is empty even if the runtime is a full JRE. This is fine but I was wondering if the exception message can indicate if the attribute value is invalid to help diagnosis. We could although I'm not sure how this could arise (as you can't set an empty profile name with the "p" option, and the "m" option to add/update a manifest also disallows empty values).

Looks like the jar tool -m option allows an entry with a space "Profile: " (a space following ":") - an existing bug then. There may be other implementation to create a jar file that doesn't do the check though.

sun.tools.jar.Main It would be helpful if the jar tool checks if the input profile name to the -p option is valid and outputs error. I considered this when updating the jar tool but decided at the time that it shouldn't know about the profile names. It would be easy to do of course.

I see no issue with the jar tool to know about the profile names as they will be standard and part of the platform. Having the jar tool to validate the profile name will help catch mistake at packaging time.
This is minor and I'm fine to revisit this in the future.
