TLS 1.3 server fails if ClientHello doesn't have pre_shared_key and psk_key_exchange_modes

TLS 1.3 server fails to handle a ClientHello message if both pre_shared_key and psk_key_exchange_modes are absent. The handshake process fails with the following exception:

javax.net.ssl.SSLHandshakeException: pre_shared_key key extension is offered without a psk_key_exchange_modes extension
