--- Comment #36 from Paul Gofman pgofman@codeweavers.com --- FWIW, here is the relevant link on Symantec Root CAs deprecation by MS: https://www.microsoft.com/security/blog/2018/10/04/microsoft-partners-with-d...
It doesn't list - V5 certificate explicitly though, while (as I read it) states that all Symantec Root CAs are to be deprecated.
I found that link through this one: https://bugs.openjdk.java.net/browse/JDK-8207258
which also links other entities' announcements deprecating Symantec CAs, and those mention G5 explicitly.
