Dear Support,

strategies, which subscribe to Instruments by the setSubscribedInstruments(Set<Instrument>, boolean) https://www.dukascopy.com/client/javadoc/com/dukascopy/api/IContext.html#setSubscribedInstruments(java.util.Set,%20boolean)
get a Java Console error as follows
2016-01-07 17:15:01.100 ERROR c - Event execution error: com.dukascopy.dds2.greed.actions.subscribe.FullDepthInstrumentSubscribeAction, message: null
java.lang.NullPointerException
   at com.dukascopy.dds2.greed.actions.subscribe.FullDepthInstrumentSubscribeAction.GA(L:53)
   at com.dukascopy.dds2.greed.actions.c.run(L:48)
   at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142)
   at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
   at java.lang.Thread.run(Thread.java:745)

Code Sniplet in "onStart(IContext context)" function: 
        
Set<Instrument> instrumentsContext =  new HashSet();
instrumentsContext.add(Instrument.EURUSD);
instrumentsContext.add(Instrument.USDCAD);
context.setSubscribedInstruments(instrumentsContext, true);

It does not happen in live at the moment as the version is still 2.45.28
Please don't roll this version out into live, this bug could terminate a lot of working strategies!

We were unable to reproduce this. Could you check that correct maven artefacts are used.

It seems like working now. Maybe it was an instrument feed problem. I will let you know if this happens again.
