org.jbpm.context.exe.ContextInstance
Maintains all the key-variable pairs for a process instance. You can obtain a ContextInstance from a processInstance from a process instance like this :
```
 ProcessInstance processInstance = ...; ContextInstance contextInstance = processInstance.getContextInstance(); 
```
