WARN TestMethodFilter - NoClassDefFoundError but verbose mode are correct

Hi, I am trying to run flacoco to generate the fault localisation for [apache-camel](https://github.com/apache/camel)

When running in verbose mode it gives me the following error. The weird thing is that on smaller projects everything seems to work. The project has been built and tests ran. Then used maven to genearte the classpath.info and pass it as per tutorial to flacoco.

Also the timeout has been set to the largest integer and the following results was received.

Reproduce the failure while running flacoco on Apache Camel with the Maven-generated classpath.info and verbose mode enabled. Start by tracing the TestMethodFilter NoClassDefFoundError shown in the reported output; done means identifying the cause and confirming a fix or clear reproduction guidance for this project.
