[ProtoPeer-general] exception when turning application to multi-threaded

[Evangelos P. - T. <E.P...@tu...>]

Hello all,

I tried to turn my application in Protopeer to a multi-threaded version. I created two new threads in every peer to deal with the concurrency of my application. However I have the following exception:

Exception in thread "Thread-548" java.lang.NullPointerException
        at java.util.TreeMap.rotateRight(TreeMap.java:2057)
        at java.util.TreeMap.fixAfterInsertion(TreeMap.java:2089)
        at java.util.TreeMap.put(TreeMap.java:559)
        at java.util.TreeSet.add(TreeSet.java:238)
        at protopeer.time.EventScheduler.enqueueEvent(EventScheduler.java:88)
        at protopeer.time.EventScheduler.enqueueEventArbitrary(EventScheduler.java:63)
        at protopeer.network.delayloss.DelayLossNetworkInterfaceFactory.sendMessage(DelayLossNetworkInterfaceFactory.java:100)
        at protopeer.network.delayloss.DelayLossNetworkInterface.sendMessage(DelayLossNetworkInterface.java:80)
        at protopeer.network.delayloss.DelayLossNetworkInterface.sendMessage(DelayLossNetworkInterface.java:103)
        at protopeer.Peer.sendMessage(Peer.java:283)

I tried to activate the multi-threading option from the configuration file but doesn't seem to help and I also do not see more threads in the process manager created for every Timer. The number of the threads are the same.

Do I miss something during in this effort?

Thank you,

Evangelos
