I had the same issue and ended up giving Amazon's Coretto OpenJDK distro a try: https://docs.aws.amazon.com/corretto/latest/corretto-8-ug/downloads-list.html and it worked (installed via rpm, switched using alternatives, on CentOS 7 x86_64)

make sure you have the identical version number for openjdk and the openjdk-debuginfo, otherwise the error will persist, I have been there :)

On Ubuntu Server 18.04, apt install openjdk-8-dbg fixed it for me
