Veja esta linha:

at dao.CadAlunoDAO.adiciona(CadAlunoDAO.java:58)

Verifique se essa linha esta referenciando algum objeto nulo.

Nota que onda dá erro é na linha 58 de CadAlunoDAO,

stmt.setLong(18, usuario.getMatricula());

E em CadAlunoGUI, tú não faz

//nas linhas 340 até 357
usuarios.setMatricula(jTextFieldXX.getText());

e nesse campo de matricula eu quero colocar pra exibir numeraçao automatica, apos a conclusao do cadastro. ai fiquei em duvida qual codigo eu uso. por isso nao especifiquei.

Outra coisa, o teu PreparedStatement não esta na mesma ordem que o teu INSERT INTO usuario.
Seria ± assim:

String sql = "INSERT INTO usuario(matricula,nome,sobrenome,sexo,dtnascimento,cpf,rg,email,telcelular,telresidencial,telrecado,logradouro,endereco,numero,bairro,cidade,estado,cep) VALUES(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)";   

//.....

stmt.setString(2, usuario.getNome());   
stmt.setString(3, usuario.getSobrenome());   
stmt.setString(4, usuario.getSexo());
