Unless x.509v3 Certificates are present in your created certificate there is no requirement that the certificate version number is 3.
If either the X.509 issuerUniqueID or subjectUniqueID fields are present the certificate must be at least version 2. However there is nothing actually stopping somebody creating a certificate with no x.509v3 extensions, and also no issuerUniqueID or subjectUniqueID, ..and having a version of 3. A version of 1 would strictly be more correct though. I don't know offhand if Keytool gives you explicit control over the version number or whether it just calculates the version from the logical certificate request data when creating the certificate. Generally all CA certificates must have extensions indicating that they are CAs, so they should have a version number of 3. Application certs on the other hand may vary depending on their content and anticipated usage.

I created X509 public keys and certificates from Sun Microsystems Keytool utility. AFAIK, it created X509v1 certificates. Please let me know if it creates v3 certificates, which in my opinion doesn't do. Looking at the on the wire message sent from client to server or otherwise, I observe Token Reference, the value of the "Valuetype" attribute in the "KeyIdentifier" element is "http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-x509-token-prof ile-1.0#X509v3" AFAIK, In X.509 Certificate Token Profile 1.1, X509v1 certificates were included in the spec, in X509 Certificate Token Profile 1.0, only X509v3 certificates were there to be used. Also, AFAIK, WSS4J supports X.509 Certificate Token Profile 1.0. Please clarify me if I am wrong. Since, X509v3 certs have some more extension elements over X509v1. It should give some error, when passing X509v1 for cryptos creation. Or, it silently use X509v1, but then the valuetype should be "#x509v1" instead of "#x509v3". There is a bit of confusion. Kindly clarify.
