Issue: Failure auto-configuring metrics for StatsD

There is an issue introduced in Spring Boot 1.4.0.RELEASE which means you get a failure when auto-configuring metrics for StatsD. Downgrading to Spring Boot 1.3.7.RELEASE makes this problem go away.

If we switch to creating our own MetricWriter the problem goes away.

Running example

./gradlew clean bootRun

Expected: Should run, log a message and exit.

Actual: Fails with the following exception:

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.boot.actuate.autoconfigure.MetricExportAutoConfiguration': Bean instantiation via constructor failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.boot.actuate.autoconfigure.MetricExportAutoConfiguration$$EnhancerBySpringCGLIB$$59d137ad]: Constructor threw exception; nested exception is org.springframework.beans.factory.BeanCurrentlyInCreationException: Error creating bean with name 'org.springframework.boot.actuate.autoconfigure.MetricExportAutoConfiguration': Requested bean is currently in creation: Is there an unresolvable circular reference?
