In DefaultSAMLTokenProvider saml2:SubjectConfirmationData populated when saml2:SubjectConfirmation Method specified as "urn:oasis:names:tc:SAML:2.0:cm:sender-vouches"

Line 131 in com.sun.xml.ws.security.trust.impl.DefaultSAMLTokenProvider.java creates KeyInfo regardless of the
confirMethod (SubjectConfirmationMethod specified in the IssuedTokenContext (ctx).
final KeyInfo keyInfo = createKeyInfo(ctx);

It's propagated to createSAML20Assertion where (it's actually handled correctly) KeyInfoConfirmationData is created for SV type, which is incorrect.
if (keyInfo != null){
keyInfoConfData = samlFac.createKeyInfoConfirmationData(keyInfo.getElement());
}
...
final SubjectConfirmation subjectConfirm = samlFac.createSubjectConfirmation(
null, keyInfoConfData, confirMethod);

SV subject confirmation should not have SubjectConfirmationData/KeyInfo in the SAML assertion.
