Currently, MacOS now fails with `java.lang.InternalError: platform encoding not initialized` and Linux fails with  `java.lang.InternalError: null property: user.dir` which are both unexpected messages.

However, this exception is never checked and thus unexpected failures occur later. NULL should be returned after the exception is thrown, so that the initialization fails with the expected error when the return value is checked.
