[11u]: RFR CSR backport: JDK-8220362: Add "POSIX_SPAWN" as valid value to jdk.lang.Process.launchMechanism on Linux

[Langer, Christoph]

Hi Andrew,

What do you mean by that? The bug JDK-8220362 [0] still has jdk11u-fix-no.

In case you approve JDK-8220362, I'll set the CSR (JDK-8220362 [1]) to finalized, referring to your approval.

Thanks
Christoph
