Problem
Recently upgraded to Stackato to 3.6.0 (from 3.4.2), pushing grails 2.4.4 app into production produced previously unseen error:
...

...Solution
Add to grails BuildConfig.groovy:
dependencies {
compile "org.springframework:spring-context:4.0.4.RELEASE"
compile "org.springframework:spring-tx:4.0.4.RELEASE"
}Specify the spring version release consistent with grails version.
Note: previous versions required to specifically define buildpack in manifest.yml:
---
applications:
- name: app
memory: 1024M
instances: 1
path: target/app-1.0.0.war
buildpack: https://github.com/cloudfoundry/java-buildpack.git

description: A simple appbuildpack attribute can now (and should) be removed
Note: this is not a issue with grails 2.5.0
Explanation
New buildpack (v3.0) downloads Spring Auto Reconfiguration 1.7.0_RELEASE, which has a different spring context version (core) than the current version of grails (in this case 2.4.4). Specifying context explicitly in grails dependencies fixes the issue.
