Opa.
Descobri bem rapidamente o erro:
Era só substituir
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/JavaWeb?useUnicode=true&amp;useLegacyDatetimeCode=false&amp;serverTimezone=UTC", "root", "");

Por:
Connection con = DriverManager.getConnection("jdbc:mysql://localhost/JavaWeb?serverTimezone=UTC", "root", "");
