NoClassDefFoundError in TestNGClassFinder.<init>

With TestNG 6.8.21, I've got this mysterious error when I try to use the test from a maven run triggered with:

mvn cobertura:cobertura -Dcobertura.report.format=xml

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test (default-test) on project nuclos-client: Execution default-test of goal org.apache.maven.plugins:maven-surefire-plugin:2.18.1:test failed: There was an error in the forked process

Even if I'm doing something nasty here, my feeling is that TestNG should recover for problem (and behave more gracefully): I don't want to do anything with org/eclipse/jgit/api/errors/GitAPIException (i.e. I'm not going to test it nor am I aware of that my tests have a dependency on this class).

In java NoClassDefFoundError is thrown when the classpath is not complete (i.e. GitAPIException is found, but it dependencies are not, it's a LinkageError). When scanning for tests, TestNG should simply emit a warning if a NoClassDefFoundError occurs, there is no need to bail out.

Agreed, TestNG should catch this exception and exit more gracefully.
