Context

Please provide below a detailed introduction to the issue itself, and describe what you were doing when the issue happened. Or, what do you want to achieve? I am using Evosuite with the following Java Project doop.zip

Steps to Reproduce

Please break down here below all the needed steps to reproduce the issue. [If possible, please upload an example of the project you are generating tests for.]

1. Unzip doop.zip
2. Run "java -jar evosuite.jar -listClasses -target C:\PATH\TO\doop" and you will see that the classes are visible to evosuite
3. Run "java -jar evosuite.jar -generateTests -class doopProj2.doopClass3 -projectCP C:\PATH\TO\doop\doopProj2\bin"
