APAR status

• Closed as program error.

Error description

• We want to be able to run liquibase-cdi both from
  unit/integration-tests as well as upon application start.
  WebSphere Application Server (WAS) however throws an error and
  it looks like an older version of OpenWebBeans included in
  WAS V8 is causing the issue.
  
  Testing a newer OpenWebBeans version (1.2.6) works fine.
  
  The startup fails with the following exception in
  SystemOut.log:
  
  java.lang.ClassCastException:
  liquibase.integration.cdi.CDIBootstrap$1
  incompatible with org.apache.webbeans.component.AbstractOwbBean
  
  at org.apache.webbeans.container.BeanManagerImpl.getReference
  (BeanManagerImpl.java:889)

  org.apache.webbeans.container.InjectableBeanManager.getReference
  (InjectableBeanManager.java:137)

  liquibase.integration.cdi.CDIBootstrap.afterDeploymentValidation
  (CDIBootstrap.java:111)

Problem conclusion

• We refactored some code to use more generic types which
  prevented the ClassCastException.
