Which ones? I did not find any other mention of the ClientID that was is
already in the Connection.setClientID() javadoc.

Where do you read that?
What's more, the test in the PR is not asserting what the spec says.
The javadoc of
https://docs.oracle.com/javaee/7/api/javax/jms/Connection.html#setClientID-java.lang.String-
is quite clear.
It throws InvalidClientIDException if the JMS client specifies an invalid or
duplicate client ID.
The test asserts that createConnection() throws an InvalidClientIDException the
2nd time a ConnectionFactory with a configured CF create a connection. That's
totally different.
