I realize folks are busy, I'll just run with this given I think we all agree immutable classpaths are better and fiddly magic in the core is bad. I'm going to remove the capability to dynamically fiddle with the project classpath and the IT for MNG-4363 will be omitted from the run for Maven 4.0.0.
