Is there a reason why the instance of a module's activator used for startup
isn't the same instance as the one used for shutdown? Looking at the
getModuleActivator()
method in Module one can see that a new instance is created each time. I
only ask because I spent forever tracking down a bug where a instance
variable was being shared unsuccessfully between the startup and
shutdownmethods.
public ModuleActivator getModuleActivator() {
try {
ModuleClassLoader classLoader = ModuleFactory.getModuleClassLoader(this);
if (classLoader == null)
throw new ModuleException("The classloader is null", getModuleId());
Class<?> c = classLoader.loadClass(getActivatorName());
Object o = c.newInstance();
if (ModuleActivator.class.isAssignableFrom(o.getClass()))
setModuleActivator((ModuleActivator) o);
}
catch (ClassNotFoundException e) {
throw new ModuleException("Unable to load/find moduleActivator: '" +
getActivatorName() + "'", name, e);
}
catch (IllegalAccessException e) {
throw new ModuleException("Unable to load/access moduleActivator: '" +
getActivatorName() + "'", name, e);
}
catch (InstantiationException e) {
throw new ModuleException("Unable to load/instantiate moduleActivator: '"
+ getActivatorName() + "'", name, e);
}
return moduleActivator;
}
