Description

The ToolRunner provided GenericOptionsParser stops parsing known options when it encounters the first unknown option string in the String[] today.

Ideally we should have it be more intelligent and sift through the whole array to pick up all opts, and not just the opts that are at the front of the invoked CLI.
