In [JDK-8352533](https://bugs.openjdk.org/browse/JDK-8352533), we print the suggestion to use VFORK in jspawnhelper misbehaves. But [JDK-8357179](https://bugs.openjdk.org/browse/JDK-8357179) deprecated VFORK! So the warning message should actually suggest using FORK. This seems to be in line with [JDK-8357180](https://bugs.openjdk.org/browse/JDK-8357180) CSR discussion and the pending [JDK-8357181](https://bugs.openjdk.org/browse/JDK-8357181) release note.
