I am writing an app to automate backtesting using API version 2.11 and I keep getting the following exception:

Exception in thread "StrategyRunner Thread" java.lang.NullPointerException

The historical data has already been downloaded into the local cache so there should not be a connection issue.

I am using the following method to run the strategy:

long ITesterClient.startStrategy(IStrategy strategy, LoadingProgressListener testerProgressListener, ITesterExecution testerExecution, ITesterUserInterface testerUserInterface) throws IllegalStateException, IllegalArgumentException

with the testerProgressListener parameter is set to null. The last 2 parameters are instances of an empty implementation of the respective interfaces.

Hello!

Please use latest SDK release (api 2.12.1, jclient 2.42.2), this should be fixed there.
