Right, the events will never be the same, but still... I wonder why
`ActionEvent` is `null` in the first place. This seems to be a bug in the JDK,
it doesn't make sense to call an action listener without a valid event.
Can you post a stacktrace when the event is `null` (and maybe return early
from the function and see, if the next event in the action listener is the
*correct* one)?---
