Inconsistent Event-subsciption in eclipse vs built mod

I have the following classes:

package mhfc.net.common.eventhandler.quests;

import cpw.mods.fml.common.eventhandler.Event;

public abstract class QuestGoalEventHandler<EventType extends Event> {
NotifyableQuestGoal<EventType> questGoal;
boolean stillActive;
protected Class<EventType> eventType;

public QuestGoalEventHandler(NotifyableQuestGoal<EventType> g,
		Class<EventType> t) {
	this.questGoal = g;
	stillActive = false;
	this.eventType = t;
}

public abstract <E extends EventType> void onEventCaught(E event);

public void setActive(boolean active) {
	stillActive = active;
}
}

package mhfc.net.common.eventhandler.quests;

import net.minecraftforge.event.entity.living.LivingDeathEvent;
import cpw.mods.fml.common.eventhandler.SubscribeEvent;

public class LivingDeathEventHandler
	extends
		QuestGoalEventHandler<LivingDeathEvent> {

public LivingDeathEventHandler(NotifyableQuestGoal<LivingDeathEvent> g) {
	super(g, LivingDeathEvent.class);
}

@Override
@SubscribeEvent
public void onEventCaught(LivingDeathEvent event) {
	if (stillActive)
		questGoal.notifyOfEvent(event);
}

}

At some point I call this piece of code:

MinecraftForge.EVENT_BUS.register(new LivingDeathEventHandler(this));

. Now the following is inconsistent.

When I execute and test the Mod in eclipse nothing special happens and everything runs smooth, the problem occurs after I built the mod and try it "in the wild":

java.lang.ClassCastException: net.minecraftforge.client.event.RenderLivingEvent$Specials$Pre cannot be cast to net.minecraftforge.event.entity.living.LivingDeathEvent
        at mhfc.net.common.eventhandler.quests.LivingDeathEventHandler.onEventCaught(LivingDeathEventHandler.java:6)

Full crash report can be found here: http://pastebin.com/8mBh7h9K

I can fully understand WHY this happens in the wild, if you can't refrain to this: http://stackoverflow.com/questions/28388034/

Why does forge think it has to call LivingDeathEventHandler.onEventCaught() for net.minecraftforge.client.event.RenderLivingEvent$Specials$Pre? When I analyze the produced classes I see the @SubscribeEvent annotation only on the method "onEventCaught(LivingDeathEvent)", so I don't see why the method should be registered for any other event at all.
