The error is there since ten years since the `posix_spawn` mechanism was initially introduced with [JDK-5049299](https://bugs.openjdk.org/browse/JDK-5049299) for JDK 8 and downported to JDK 7 :)

In JDK 13 it only became the default mechanism on Linux.

And although LTS releases are not different from any other releases (reference pending :) it was only detected when migrations to JDK 17 finally started to ramp-up.
