"install-forge" install-command failed on java8 image #3585
Description
Describe the problem
I've been running 1.12.2 server using java8 image and it worked just fine for months until I start facing this issue that seems to be unfixable and I found this participular issue: itzg/docker-minecraft-server#3582, but it is for latest image. Seems like they didn't update java8, java17, etc to fix this issue. Currently this issue made all of the java versions except latest unusable until this issue similar to itzg/docker-minecraft-server#3582 is fixed.
