I have some problems loading the feed price all currencies with jForex SDK 2.44.7. Please fix it.
com.dukascopy.api.JFException: com.dukascopy.charts.data.datacache.DataCacheException: Failed to load in-progress candle data in timeout period [AUD/CAD, 4 Hours, Bid]
API Support:
This happens because data loading took too long.
That can be solved by loading fewer instruments at once and restarting download with other instruments when the first ones have finished.
Marston:
Intraday is too long??
API Support:
Please run the JClient with open java console and post console output here.
Here is a descriptoin on how to enable the console:
https://www.java.com/en/download/help/javaconsole.xmlPlease note that if there are charts open, the platform will load all the data for those instruments.
Speed of data loading may also be limited due to the internet connection speeds.

I have the same problem with history.getBar(instrument, period, OfferSide.BID, 1);

If I revert to 2.43.2, the same code works fine all the time in my unit tests! Is there a regression in 2.44.7?
My code is simple and I load only one instrument in my unit testing.
duka.instance.startStrategy(new GetContextForTesting());
IHistory history = GetContextForTesting.getHistory();
Instrument instrument = DukaTools.subscribeToInstrument(GetContextForTesting.getContext(), "EUR", "USD");
IBar prevBar = history.getBar(instrument, period, OfferSide.BID, 1);
I am going back to 2.43.2 for now...
PS: my connection speed is 250Mbit/s, and that would not explain why it works with 2.43.2

I updated my POM today and I tested with 2.45.2. The same problem is still there and can be reproduced each time I run my unit test.
So the issue is there with 2.45.2 and 2.44.7, but it works fine with 2.43.2. I will stay on 2.43.2 until this problem is fixed.
API Support:
We were unable to reproduce this. Please provide full code example.

Ok. The following basic unit test works fine with 2.43.2, but not with 2.44.7 or 2.45.2:
