BouncyCaste: How to add an OID (for example duidNumber) to the Subject in a CSR request?

Using the BouncyCastle library, I need to include in the Subject a CSR request the following OID: 1.3.6.1.1.1.1.0 which corresponds to the > uidNumber . The subject I have it in the following way:

X500Principal subject = new X500Principal("CN=CNdePrueba,O=EntidadDePrueba,OU=OrganizacionPrueba,[email protected], UIDNumber=123456, UID=tipDocumentPrueba");

And the Exception is this:

Exception in thread "main" java.lang.IllegalArgumentException: improperly specified input name: CN=CNdePrueba,O=EntidadDePrueba,OU=OrganizacionPrueba,[email protected], UIDNumber=123456, UID=tipDocumentPrueba

The point is: how do I add that OID (1.3.6.1.1.1.1.0) so that the subject accepts it?
