Description

The Java Action docs say:

The main Java class must not call System.exit(int n) as this will make the java action to do an error transition regardless of the used exit code.

http://oozie.apache.org/docs/4.2.0/WorkflowFunctionalSpec.html#a3.2.7_Java_Action

This has not been true for quite some time. Oozie counts System.exit(0) as OK and non-zero values as the ERROR transition.
