Hi,

I have downloaded the JForex SDK 3 from https://www.dukascopy.com/wiki/en/devel ... jforex-sdk

When running the jforex.tester.client.gui.TesterMainGUIMode - I got the following error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/dukascopy/api/system/ISystemListener : Unsupported major.minor version 52.0


1. From what I understand, it means that the minimal JDK should be 1.8 but in the JForex-3-SDK pom.xml it states
               <source>1.7</source>
               <target>1.7</target>


Probably needs to be updated?


2. Is it OK to use JDK 9? I have noticed that in the latest JForex changelog you mentioned support for Java 9.
Can I use Java 9 to write my strategies and than test them in the JForex platform?

Thanks.

Yes. JForex SDK requres JRE 1.8 installed on your PC. Issue happens because you are trying to run SDK on JRE 1.7. JRE can be specified in your IDE Run Configurations.

Strategy API/Indicator API works on Java 7, we plan to implement Java 8 support in future. Exact timeline depends on other workload.
