[jira] [Created] (BROOKLYN-125) attributeWhenReady blocks entity stop

Svetoslav Neykov created BROOKLYN-125:
-----------------------------------------

             Summary: attributeWhenReady blocks entity stop
                 Key: BROOKLYN-125
                 URL: https://issues.apache.org/jira/browse/BROOKLYN-125
             Project: Brooklyn
          Issue Type: Bug
            Reporter: Svetoslav Neykov


Using attributeWhenReady in shell.env blocks stop. A sample blueprint:

```
services:
- type: <slow entity, i.e. brooklyn.entity.webapp.tomcat.TomcatServer>
  brooklyn.config:
    shell.env:
      var: $brooklyn:component("fast").attributeWhenReady("host.address")
- type: brooklyn.entity.machine.MachineEntity
  id: fast
```

The `fast` entity is quick to disappear, so attributeWhenReady will block indefinetly when setting up the environment for the stop calls.
