Hi,

both errors have in common that there are about an change of allowed hostnames. But as for the second bug there is an big mistake. The underscore is allowed for SRV and CNAME but not for A records. For SRV records it is wide used in LDAP records for MS Domain System (PDC). But the Subject Alias is about valid hostnames so only the Number as you mentioned should be allowed
as first character.

Hi all,

just a question, I hope this is the correct mailing list.

There is https://bugs.openjdk.java.net/browse/JDK-8016345, which is about DNSName not accepting host names with leading numbers, which is valid according to https://tools.ietf.org/html/rfc1123 (Section 2.1).

This bug was marked as a duplicate of https://bugs.openjdk.java.net/browse/JDK-8007706, which I do not understand - what do these errors have in common?

I try to understand why JDK-8016345 was marked as will-not-fix. Are there any reasons to not fix the parser in DNSName.java (because the fix itself looks trivial)?

Thank you, and Kind Regards, Thomas
