Viacheslav Kabanovich commented on JBIDE-11867:
-----------------------------------------------
I think that we cannot consistently check if there is an observer to receive an event.
In the case, given in description, the event can be sent to the observer by
{code}
eventLog.select(new NowLiteral()).fire();
{code}
Runtime does not fail, when there is no observer for a fired event. Events may be fired by a framework application to be caught in a custom application that has it in its classpath.
I will create a new feature request about the warning, and resolve this issue as what it declares by its title is fixed.
