Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Run processes under JRuby.

This implementation relies on Open3.capture3 to run commands and capture results. In contrast to the POSIX runner this cannot be used in an asynchronous manner as-is; implementing that will probably mean launching a thread and invoking #capture3 in that thread.
