Severe WSS0216 Error Logged When Validating Signature

[Tomas-Kraus]

Observed using the version of Metro released included in Glassfish 4.1. The log indicates Metro/2.3.1-b419 (branches/2.3.1.x-7937; 2014-08-04T08:11:03+0000). Investigated using the sources labeled 2.3.2-20150304.231348-334.

When validating the signature of a SOAP message signed by a public key that does not have a certificate in a TrustStore or CertStore provided by the CallbackHandler, a SEVERE error is logged of form:

WSS0216: An Error occurred using CallbackHandler for : Sun RSA public key, 2048 bits
  modulus:
...
  public exponent: ...

This seems to be coming from line 2231 of com.sun.xml.wss.impl.misc.WSITProviderSecurityEnvironment , in getCertificate(). The more meaningful exception thrown from there is logged as FINE in com.sun.xml.ws.security.opt.impl.incoming.Signature .process() line 289.

Other than the logged error, there does not seem to be any problems; the signature is validated properly and the SOAP message is received by our application code.

There are two related issues here:
1. I don't believe this is an error case. (For instance, in our use case, a certificate signed by a CA we trust is provided in the SOAP message.)
2. The SEVERE error logged does not provide any useful clues as to what the problem is or where it is occurring.
