Some JVMs pass through `home` as a derivation rather than as a string, as `openjdk` does. Since the module option for session variables expects a string, this is a type error. I suspect that this incorrect, and have changed the assignment here to coerce the `cfg.package.home` attribute to a string to be safe. After discussing with @NobbZ, we have decided it is best to mitigate this problem in HM rather than to make potentially breaking changes to Nixpkgs. Please do mention if you think we ought to propose a change to Nixpkgs instead.
