[java] For a boolean field, what is the naming convention for its getter/setter?

Maybe it is time to start revising this answer? Personally I would vote for setActive() and unsetActive() (alternatives can be setUnActive(), notActive(), disable(), etc. depending on context) since "setActive" implies you activate it at all times, which you don't. It's kind of counter intuitive to say "setActive" but actually remove the active state.

Another problem is, you can can not listen to specifically a SetActive event in a CQRS way, you would need to listen to a 'setActiveEvent' and determine inside that listener wether is was actually set active or not. Or of course determine which event to call when calling setActive() but that then goes against the Separation of Concerns principle.

A good read on this is the FlagArgument article by Martin Fowler: http://martinfowler.com/bliki/FlagArgument.html

However, I come from a PHP background and see this trend being adopted more and more. Not sure how much this lives with Java development.
