Hello, I've created a scheduler service and noticed a memory leak. I'm using
the exact code below to perform the test. I read an article related to class
reloading causing memory leaks,
http://tapestry.apache.org/class-reloading.html However, I don't really
understand what is being implied. I'm wondering if I'm doing something wrong
to cause this issue. After running the app from 14:56:23.026 through
15:16:30.222 with one second memory printouts I've noticed the following
loss.
Available memory JVM (bytes) 8826784 14:56:23.026
Available memory JVM (bytes) 6906536 15:16:30.222
//appmodule
public static void bind(ServiceBinder binder) {
binder.bind(SchedulerService.class, SchedulerServiceImpl.class);
}
@Startup
public static void initApplication(SchedulerService scheduler) {
scheduler.init();

Runtime.getRuntime().freeMemory());
