AnnotationTypeMismatchException in jcommander

[rpii]

There was a previous report of something similar to this issue but I am getting it with jcommander 1.72: This is code that was working before a dependency upgrade changed the jcommander version from 1.64. The file mentioned does exist.

Not really sure what is causing this.

Its seems to have to do with this parameter in Selenium:

  /**
   * Hub specific json config file to use. Defaults to {@code null}.
   */
  @Parameter(
    names = "-hubConfig",
    description =  "<String> filename: a JSON file (following grid2 format), which defines the hub properties",
    validateValueWith = FileExistsValueValidator.class
  )
