Hey I just made a pull request

Description

When updating to this version of Flo, our jobs failed to execute as it was unable to find the ForkingExecutor class. This was due to the arguments passed in to the classPath variable were not absolute Paths.

Have you tested this? If so, how?

We have tested this by running it locally, its not possible to unit test as the class path is determined by the environment.
