/**
* Saves system properties before the annotated feature method (including any setup and cleanup methods) gets run,
* and restores them afterwards.
*
* <p>Applying this annotation to a spec class has the same effect as applying it to all its feature methods.
*
* <p><strong>Note:</strong> Temporarily changing the values of system properties is only safe when specs are
* run in a single thread per JVM. Even though many execution environments do limit themselves to one thread
* per JVM, keep in mind that Spock cannot enforce this.
