Dear users@groovy.apache.org, as described in the question on SO http://stackoverflow.com/questions/42648766/groovy-listenerlist-generated-firexxx-method-stops-working and confirmed by @aalmiray the fireWhatever() method generated when using @ListenerList annotation stops working.
@aalmiray s code as posted in his reply reproduces the problem with Groovy 2.4.7 and I confirmed it with 2.4.8 running it in groovyConsole import groovy.beans.ListenerList interface MessageListener { void messageReceived(byte[] msg) } class MessageProducer { @ListenerList List<MessageListener> listeners void produce(String msg) { fireMessageReceived(msg.getBytes()) } } producer = new MessageProducer() producer.addMessageListener({ println it } as MessageListener) producer.produce('Groovy') The stacktrace is Exception thrown java.lang.NoSuchMethodError: MessageProducer.fireMessageReceived([B)V at MessageProducer$fireMessageReceived$0.callCurrent(Unknown Source) at MessageProducer.produce(ConsoleScript0:12) at MessageProducer$produce.call(Unknown Source) at ConsoleScript0.run(ConsoleScript0:18 Are we doing something wrong or is this a bug? Thank you Frigo Pratser
