/approval request That fix is required for Java to launch new processes when running inside QEMU user space emulation. It is a requirement for some platforms (like riscv or s390x) as hardware or VMs are not largely available, and QEMU is the only available solutions on many CIs. The approach has been in JDK 21 and later for some time, and it's been validated to work.
The risk is also minimal since the patch only makes sure to follow the specification for posix_spawn and execve, which we didn't follow before.
The backport wasn't clean, but the conflicts are minimal and the logic straightforward.
