I had a chance to clone the illumos zone to a separate server and upgrade postgres to latest 10.5.
The results are the same:
Postgres logs "could not accept SSL connection: ccs received early"
The Java code throws the exception:

That way you can see if it's something in your certificate creation
process that causes trouble.
