I think for TLS 1.3, the contents of the ticket should be independent 
from the property.  The property names 
"jdk.tls.server.enableSessionTicketExtension" and 
"jdk.tls.client.enableSessionTicketExtension" are about the ST 
extension.  TLS 1.3 session resumption uses a different mechanism.

I may missed something.  Why you think the content of the ticket 
depending on the property?

Thanks,
