[robocup-rescue-s] URGENT: Map generator for day 4

Hi everyone,

Tomorrow we will be using maps generated with a new map generator. These
maps have some unusual features, such as dead ends and long branching
roads that do not connect back to the rest of the map, and this may
cause problems for some teams.

I have just run a test map with all teams using today's code. Most teams
worked perfectly with the new map, but three teams crashed on startup
with a NullPointerException (MRL,Seu and TsinghuaAeolus).

I have attached the test map. Please test your agents with this map and
make sure they work correctly! Also, if you manage to find a problem
with the map (I hope you don't!) then please tell me as soon as possible
so I can fix it.

Unless someone finds a problem with the map, then if your agents crash
tomorrow you will get zero for the map. I strongly urge you to make sure
that your agents work correctly on this test map.

If any agents crash on startup tomorrow with the same error I saw
tonight then you *will* get zero. The stack trace (it is mostly the same
for all three teams) is as follows:

Exception in thread "main" java.lang.NullPointerException
         at yab.agent.DisasterSpace.update(DisasterSpace.java:345)
         at yab.agent.DisasterSpace.<init>(DisasterSpace.java:103)
         at yab.agent.Agent.<init>(Agent.java:33)

         at yab.agent.PlatoonAgent.<init>(PlatoonAgent.java:64)

yab.agent.AbstractFireBrigadeAgent.<init>(AbstractFireBrigadeAgent.java:15)
         at

         at MRL.Main.connectAgent(Main.java:51)
         at MRL.Main.connectAgents(Main.java:35)
         at MRL.Main.main(Main.java:26)

Cameron.
