http://nagoya.apache.org/bugzilla/show_bug.cgi?id=9750 Using AsynchAppender in logging configuration prevents virtual machine from exiting ------- Additional Comments From [EMAIL PROTECTED] 2002-06-10 17:53 ------- Potential solution: I believe that the VM is continuing execution because the thread created by AsyncAppender is not a daemon thread. If this thread were to be set as a Daemon thread then the VM should be able to exit properly. Here is a change to the constructor of Dispatcher (internal class in AsyncAppender) that would accomplish this: Before: Dispatcher(BoundedFIFO bf, AsyncAppender container) { this.bf = bf; this.container = container; this.aai = container.aai; // set the dispatcher priority to lowest possible value this.setPriority(Thread.MIN_PRIORITY); this.setName("Dispatcher-"+getName()); // set the dispatcher priority to MIN_PRIORITY plus or minus 2 // depending on the direction of MIN to MAX_PRIORITY. //+ (Thread.MAX_PRIORITY > Thread.MIN_PRIORITY ? 1 : -1)*2); } After: Dispatcher(BoundedFIFO bf, AsyncAppender container) { this.bf = bf; this.container = container; this.aai = container.aai; this.setDaemon(true); // set the dispatcher priority to lowest possible value this.setPriority(Thread.MIN_PRIORITY); this.setName("Dispatcher-"+getName()); // set the dispatcher priority to MIN_PRIORITY plus or minus 2 // depending on the direction of MIN to MAX_PRIORITY. //+ (Thread.MAX_PRIORITY > Thread.MIN_PRIORITY ? 1 : -1)*2); } This of course leaves the appender vunerable to the possibility of a VM shutdown resulting in logging message loss. If this is an issue, then perhaps a finalizer could be added that would call the dispatcher's close() method? -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
