## Summary
- Restore historical `Runtime.exec(String)` whitespace tokenization when
`argumentsInFields` is false.
- #7565 changed `exec(process[0])` to `exec(new String[] {process[0]})`,
which treats the entire command line (e.g. `/bin/echo hop-single`) as the
executable name, so stdout is null and CI fails on Linux.
- Tokenize with `StringTokenizer` (same as the old `Runtime.exec(String)`
behavior) before calling `exec(String[])`, avoiding the deprecated String
overload.
