> When HAServiceProtocol.monitorHealth throws a HealthCheckFailedException, the
> actual exception from protocol buffer RPC is a RemoteException that wraps the
> real exception. Thus the state is incorrectly transitioned to
> SERVICE_NOT_RESPONDING
> {noformat}
> HealthMonitor.java
> doHealthChecks
> try {
> status = proxy.getServiceStatus();
> proxy.monitorHealth();
> healthy = true;
> } catch (HealthCheckFailedException e) {
> .....
> enterState(State.SERVICE_UNHEALTHY);
> } catch (Throwable t) {
> .....
> enterState(State.SERVICE_NOT_RESPONDING);
> .....
> }
> {noformat}
