container exits on stops/restarts

[mbravorus]

Describe the bug

When attempting to stop or restart the server, container exits

To Reproduce Steps to reproduce the behavior:

1. launch the server with recommended docker run command
2. wait until server finishes starting up
3. enter a stop or even better, a restart command
4. See error:

./docker-entrypoint.sh: line 16: exec: serve: not found

Expected behavior Expected behaviour is for server to restart

Additional context FWIW, this is happening on Debian 10 but I don't think it's relevant. I can see two parts here. About start.sh I'm not sure where that is coming from. But about serve not found I'm pretty sure that's because you use CMD+ENTRYPOINT format and thus $@ doesn't contain the name of the script itself, only the serve parameter.

Can we fix this, because otherwise a simple thing such as a server restart becomes quite involved?

ok, the line about start.sh not found is coming from default spigot config, so we can ignore that, but the main point remains
