ERR undefined method `[]' for nil:NilClass during Spring Application deployment

[jhiemer]

Hi,
I have an application running, which could be deployed till yesterday without any issues. Today I am getting the following exception:

My deployment manifest.yml looks like that:

instances: 1
timeout: 180
memory: 1024M
applications:
## Web
- name: web
  host: dev-api
  domain: bla.com
  path: target/web.war
  buildpack: https://github.com/cloudfoundry/java-buildpack.git
  services:
  - mongodb
  - postgresql
  - rabbitmq

Any idea what's wrong? :-( Tried rebooting runner/api/api_worker and changing the organisation/space, without any different result.

This seems to be an issue with gemfire in tomcat:

@nebhale is this a bug in the buildpack? Java Buildpack Version: 6f3de1a

We also faced same error while deploying simple spring app.
I am adding log snippet here

This seems to related to a recent commit here:

two days ago.

[ramonskie]

add @nebhale & @cgfrost as participant

[cgfrost]

I'm looking at this now, I will back the commit out unless the solution can be found quickly.
