The failing code is triggered by this line: return String.format("%1d%X...

To be clear, these are "black box" assertions inside implementations (checking invariants, etc) not the assertions defined by the JUnit tests themselves. Of course, I'd like to catch any...

I would like to provide diagnostic information about what JAXP implementation is in use, and which JAR file it was loaded from.
