Post subject:  IClient.setSubscribedInstruments(..) error
I use two day old Jforex_SDK and try IClient. After connection I want to subscribe instrument. Code is from this page:

https://www.dukascopy.com/wiki/en/devel ... nstruments

Set<Instrument> instruments = new HashSet<Instrument>();
instruments.add(Instrument.EURUSD);
LOGGER.info("Subscribing instruments...");
client.setSubscribedInstruments(instruments);

I receive this error:

This happens when correct guava library is missing from jClients dependencies. Forcing usage of different guava version may also cause this.

You are right. It was different guava version conflict. I made several exlusions in pom.xml and all is OK. Thank you.
