Hi,

I got a NullPointerException when using DefaultApplications.getEnvironments:

It seems to happen on an application without user provided environment variables.

What version of cf-java-client are you using? What version of CF are you connecting to? (output of cf curl /v2/info would help). What version of Spring Boot is your app using, if you're using Boot. Thanks

Sorry, I should have given the versions right away.

Version of cf-java-client: 5.9.0.RELEASE.

Output of cf curl /v2/info (I replaced some private values with ---):

{
  "name": "---",
  "build": "",
  "support": "",
  "version": 0,
  "description": "",
  "authorization_endpoint": "---",
  "token_endpoint": "---",
  "min_cli_version": null,
  "min_recommended_cli_version": null,
  "app_ssh_endpoint": "---",
  "app_ssh_host_key_fingerprint": "---",
  "app_ssh_oauth_client": "ssh-proxy",
  "doppler_logging_endpoint": "---",
  "api_version": "2.182.0",
  "osbapi_version": "2.15",
  "routing_endpoint": "---",
  "user": "---"
}

And I'm not using using Spring Boot.

Apologies for the delayed response. Would you be able to follow these instructions, step #5, and capture debug logs and wire traces, specifically when it tries to fetch the environment. It is possible that the server is returning something unexpected, and the traces would allow us to see what is returned. Thanks
