It’s for diagnostic, the ldap server was designed to shadow support ldap tests, it should be a black box to ldap client unless there is intent interaction per test, so in most case the server side exception should not affect test itself, just for diagnostic.
Yep, putting stack traces into log sounds good to me

You are correct, it’s a buffer for a single message, so should be singular, getMessages() should also be rename to getMessage() to avoid confusion

To prevent modification to original LdapMessage, yep, javadoc could be improved to make it clear

Yes, I believe that should work since we limited the payload length presentation <= 4 bytes
