Re: run-program issues with OpenJDK 11

I just tested this on a fresh Debian Buster VM (to rule out anything weird from my environment) with openjdk-11-jdk-headless and ABCL 1.7.1 and ended up with the same results:

+ The prebuilt jar is unable to use sys:run-program at all.

+ When built from source, sys:run-program works, but sys:process-pid does not.

lisp-implementation-version:

"1.7.1" "OpenJDK_64-Bit_Server_VM-Debian-11.0.7+10-post-Debian-3deb10u1" "amd64-Linux-4.19.0.9-amd64"

Mark: I just realized that your use of swank-backend:getpid doesn't match what I was trying to do. Swank's getpid gets the PID of the current process, but I was trying to get the PID of a process started with (sys:run-program ... :wait nil) using sys:process-pid.
