Giant long file paths like file:/home/mbeckerle/dataiti/git/daffodil/eclipse-projects/target/test/edu/illinois/ncsa/daffodil/section06/namespaces.tdml

These clutter the error messages, and all but the section06/namespaces.tdml are noise.

Almost nothing can be viewed without scrolling the window/panel to the right so as to get past these giant paths. Or alternatively they wrap around line after line.

Any given path being displayed can have whatever the longest prefix of it that matches a location on the classpath, that longest prefix can be removed without much loss of information content.
