Lifetime of NetworkTableEvents and associated data?

[brettle]

In Java, when a listener is called is there any limit on how long the data contained in and referred to by NetworkTableEvent is valid? For example, if my listener just saves a reference to a kValueRemote event on a double[] topic, should event.valueData.value.getDoubleArray() continue to return the value associated with that event even after all of the topic publishers/subscribers are closed and the listener is removed? Or does the listener need to copy the data it cares about before returning?

In Java, the lifetime is forever; Event objects passed to the callback are not reused (new objects are created for every event) and can be retained/used indefinitely by the callback function.
