Downport JDK-8212828 (posix_spawn on Linux as non-default) to 11u

[Thomas Stüfe]

Hi all,

I would like to have this patch in 11u too, so I just did a 11u
downport request.

Our agreement was that launchMechanism=POSIX_SPAWN would stay as
optional non-default value for jdk12, and at the start of JDK13
development we would switch the default to posix_spawn.

I would like to see this non-default-but-possible-to-set option in 11u
too, just to broaden the test surface. We'd get more testers that way.

What do you think, does that make sense?

Thanks, Thomas
