Thanks @tbouron - LGTM. Once jenkins has finished running the tests, I'll merge this.

I've created https://issues.apache.org/jira/browse/BROOKLYN-430 to track this in brooklyn, which just links to jclouds https://issues.apache.org/jira/browse/JCLOUDS-1229.

The test failure is unrelated, and should be investigated/fixed separately:

java.lang.AssertionError: entity=Application[802qtu86]; attribute=Sensor: service.state (org.apache.brooklyn.core.entity.lifecycle.Lifecycle) expected [running] but found [on-fire]
	at org.apache.brooklyn.core.entity.ApplicationLifecycleStateTest.assertHealthContinually(ApplicationLifecycleStateTest.java:196)
	at org.apache.brooklyn.core.entity.ApplicationLifecycleStateTest.testStartsThenChildFailsButWithQuorumCausesAppToSucceed(ApplicationLifecycleStateTest.java:170)

@tbouron can you trigger jenkins to build again please, e.g. by doing git commit --amend; git push -f
