CSR for posix_spawn on JDK 12

[Thomas Stüfe]

David, Roger, Alan,

thank you for clarifying all this, and sorry for my confusion.

I found describing jdk.lang.Process.launcMechanism especially
problematic since to understand it one must understand the details of
fork/vfork plus know the details of the underlying implementation of
the libc.

Using this feature with one libc is completely fine, with a different
version may not be recommended. To distill that into a few lines for
customers is difficult, especially if you do not want to lead them
astray (in our port, we tend to not to mention diagnostic features
with foot-shooting-opportunities :).

But part of my confusion was that it was not clear what more was
needed from me; but now I see the CSR
(https://bugs.openjdk.java.net/browse/JDK-8214511) has already been
approved by Joe.

So all that is needed from me now is to finish the release note at
https://bugs.openjdk.java.net/browse/JDK-8214454. I will do this
presently.

Thanks for all your help and explanations.

..Thomas
