10.2.3. The Event interface - provided executor cannot execute observers notification ------------------------------------------------------------------------------------- Key: CDI-544 URL: https://issues.jboss.org/browse/CDI-544 Project: CDI Specification Issues Issue Type: Clarification Reporter: Tomas Remes {quote} If the provided executor cannot execute observers notification, an IllegalArgumentException is thrown. {quote} What does it mean "cannot execute"? I am not really sure. Does it mean the observer throws an exception which should be wrapped in IAE? This would likely contradict {{10.5.1. Handling multiple exceptions thrown during an asynchronous event}}. Maybe this sentence could be omitted.
