two similar issues at once and cited the wrong one. Sorry about that. But it looks like I may have solved this issue (and possibly created others, but that is another story) – my project also uses CXF and WSS4J, and it looks like the WSS4J initialization code
doesn’t properly initialize everything in OpenSAML, particularly the parser pools. They’ve put a fix in their bootstrapping code, which for the moment I’ve cribbed and stuck in my own code; that’s gotten me past the immediate issue.<o:p></o:p></span></p>

Ok, since you mention a main() class, I assume this isn't a webapp, and so is a simple, flat classloader hierarchy.<br>

<p class="MsoNormal"><span style="color:windowtext">What I do think it could be is that I’m missing dependencies. In v2, I only needed a single opensaml dependency in my pom file. Is the same true in v3? I had only opensaml-core listed, and have just added
opensaml-xmlsec-api, opensaml-profile-api, opensaml-security-api, opensaml-storage-api, and opensaml-saml-api, but I’m still having the same issue. Did I miss a library?

Yes, you definitely need to add the corresponding -impl modules. For SAML and the other schemas (XML Signature, Encryption, etc) that's where all the object provider impls are located. You can't do much SAML without those.<br>
<br>
That begs the question: It seems like you were trying to marshall an Assertion, and I don't see how you could actually an actual instance (as opposed to a null reference to the Assertion inteface) without e.g. opensaml-saml-impl.<br>
<br>
<br>

<p class="MsoNormal"><span style="color:windowtext">Or am I going up the wrong tree here?</span><o:p></o:p></p>

If you don't have any -impls, that would definitely be a problem. However, I'm not immediately connecting that to the error you reported. The global ParserPool is inited as a part of opensaml-core, so that should be there with just opensaml-core as a dependency.
But maybe it's a non-obvious issue. Try adding the -impl's as deps and see how far that gets you.<o:p></o:p></span></p>
