Can't start akhq. Tried in Windows and in Ubuntu under WSL, my config file and example from github - same result. Java version - openjdk version "11.0.13" 2021-10-19 in Ubuntu and openjdk version "16.0.1" 2021-04-20 in Windows
Starting it with java -Dmicronaut.config.files=/opt/akhq/application.example.yml -jar akhq-0.21.0-all.jar
Full output is:

Can you provide the application.yml please ?

[ant0nk]

My file is:

micronaut:
  security:
    enabled: disabled

  server:
    context-path: "" # if behind a reverse proxy, path to akhq without trailing slash (optional). Example: akhq is
                     # behind a reverse proxy with url http://my-server/akhq, set context-path: "/akhq".
                     # Not needed if you're behind a reverse proxy with subdomain http://akhq.my-server/
akhq:
  # list of kafka cluster available for akhq
  connections:
    my-cluster-plain-text: # url friendly name for the cluster (letter, number, _, -, ... dot are not allowed here)
      properties: # standard kafka properties (optional)
        bootstrap.servers: "172.19.112.16:9092"
      schema-registry:
        url: "http://172.19.112.16:8085" # schema registry url (optional)
        type: "confluent" # schema registry type (optional). Supported types are "confluent" (default) or "tibco"
 

And example file that I tried without any changes I downloaded from https://github.com/tchiotludo/akhq/blob/dev/application.example.yml

[tchiotludo]

  server:
    context-path: "" # if behind a reverse proxy, path to akhq without trailing slash (optional). Example: akhq is
                     # behind a reverse proxy with url http://my-server/akhq, set context-path: "/akhq".
                     # Not needed if you're behind a reverse proxy with subdomain http://akhq.my-server/

just remove this part and it will work I think

That helped. Thanks.
