Colm O hEigeartaigh resolved WSS-611.
-------------------------------------
    Resolution: Fixed

> CAs with the NameConstraint extension cause exceptions when verifying trust
> ---------------------------------------------------------------------------
> 
> Key: WSS-611
> URL: https://issues.apache.org/jira/browse/WSS-611
> Project: WSS4J
> Issue Type: Bug
> Components: WSS4J Core
> Affects Versions: 2.1.10
> Reporter: Richard Porter
> Assignee: Colm O hEigeartaigh
> Fix For: 2.2.0, 2.1.11
> 
> 
> When a CA with NameConstraints is in the truststore, it causes a failure with any \
> crypto Cert provider. The underlying cause is an {{IllegalArgumentException}} \
> thrown because the Sequence data has been encoded as an Octet String and it is not \
> being correctly decoded. While the relevant RFCs are a bit ambiguous with regard to \
> extensions and whether they are all encoded as Octet Strings or not, the \
> documentation on Java's implementation of \
> [X509Extension|https://docs.oracle.com/javase/8/docs/api/java/security/cert/X509Extension.html#getExtensionValue-java.lang.String-] \
> are unambiguous: it will be a "DER-encoded OCTET string for the extension value. \
> Beneath this issue lies another, the fact that the Sun default implementation of \
> PKIX path validation does not support TrustAnchors with NameConstraints attached. \
> So fixing the first issue also requires conditionally constructing TrustAnchors \
> with NameConstraints or with null.
