In prepareInternalNetwork, Exceptions creating integration bridge are ignored

public void prepareInternalNetwork(Node node) {
try

{ this.createIntegrationBridge(node); }

catch (Exception e)

{ logger.error("Error creating internal network "+node.toString(), e); }

ProviderNetworkManager.getManager().initializeFlowRules(node);
}

The exception in createIntegrationBridge is ignored. initializeFlowRules will fail if the integration bridge does not exist.
