+/**
+ * CauseFailureDecorator applies decorations to {@link BrokerLifecycleAware} tests, so that they may use different failure
+ * mechanisms. It is capable of detecting when a test case uses in-vm brokers, and setting up an automatic failure
+ * for those tests, so that the current live broker can be shut-down by test cases. For external brokers, automatic
+ * failure could be implemented, for example by having a kill script. At the moment this sets up the failure to prompt
+ * a user interactively to cause a failure, using {@link CauseFailureUserPrompt}.

+ * @todo Slight problem in that CauseFailureInVM is Qpid specific, whereas CauseFailureUserPrompt is not. Would like the
+ * failure decorator to be non-qpid specific so that it can test failure of any JMS implementation too. Either pass
+ * in class name of failure mechanism, set it up in the in-vm decorator instead of here but with prompt user as the
+ * default for when the in-vm decorator is not used?
