<p>I have a custom data connector that packaged it's XSD file into the jar and it loaded fine with 4.1.* (I think any of them, but I don't have good tracking on that). I never upgraded to 4.2, but I was working on upgrading to 4.3, and when the attribute-resolver
is loading it fails to find the schema files (along with associated errors). I think this logging is the issue:<br>

<p>I am guessing this is just me not keeping track of changes, and that it's probably a simple packaging change or syntax change, I need to make to my data connector, but a quick googling didn't help me identify what has changed, perhaps the way to specify
the pathing has changed or maybe I need to place the schema file into an appropriate Shibboleth location separate from it being inside the jarfile. </p>
