Você está lançando a exceção novamente de dentro do método getManaget() ?

porque como vc está fazendo um catch dentro desse método, a exceção pode estar se esculhambando ai.

o teu catch tem que ter isso um throw.

}catch(Exception e){ ---- throw e; }

Cara, sinto muito, mas eu não to conseguindo visualizar o problema.

Fiz a mesma coisa aqui e não tive problemas.

Mas como não custa arriscar algumas hipoteses, lah vai:

  • talvez não esteja retornando uma exception e sim um Error ou Throwable
  • talvez a classe PersistenceException esteja errada e não está exibindo a mensagem que vc passa pra ela como parametro
  • talvez tenha um ser maligno no seu computador XD
  • talvez mais alguém pudesse ajudar :wink:
