Javadoc

Alternative version of exec() that retrieves stdout and stderr into the StringList objects provided. This is a convenience function that handles simple exec() calls. If the results will be more than a couple lines, you shouldn't use this function, you should use a more elaborate method that makes use of proper threading (to drain the shell output) and error handling to address the many things that can go wrong within this method.
