@fmeden Did you change the architecture you're running it on? That's the default error message if one of the libraries used by an app isn't arch-compatible
@mheiber didn't touch the image at all, it's just been rebuilt with a fresh pull of the base
@mheiber oh I didn't even realise that docker images can target specific architectures.
anyhow I don't think that's the problem, changing the location of the binary to /usr/local/openjdk-11/bin/java fixed it immediately. there was no file under the path /usr/bin/java anymore
