I try to start Quarkus with the --debug param and I get the following:

```

I start the docker container with these ports: -p 8787:8787 -p 8443:8443 -p 8080:8080  
the 8080 & 8443 work

Any ideas?

Try to set these env vars:

```auto
DEBUG: 'true'
DEBUG_PORT: '*:8787'

```

Also, I don’t use the `--debug` switch.

I have already tried with the variables, that wasn’t the problem. However, your answer helped me, because I was missing the `*:` in front of the port and apparently with the new java that’s mandatory.  
So thank you!
