I have a strategy which consists of a single java file for the strategy including two inner classes, which was testing fine earlier today. But now, as it is getting more complete, I get a type of error which offers me no clue as to its cause or how to fix it.

Specifically, when I compile the strategy, it claims it has been successful, and produces a jfx file. But it immediately creates multiple messages in the Messages tab which consist solely of the two characters "-1".

Then when I try to run the strategy, I get more of the "-1"s with a single message "Class not accepted" as well.

When I try to stop the strategy to attempt to fix the problem, it just produces a couple more "-1"s each time and I have to terminate the application.

PLEASE provide some sort of workaround so that I can get my working system up and trading for real.

[Note that I had identical problems before and after an update of the jforex platform today, and identical problems on demo and live platforms].

Please provide an example that would reproduce the issue. If it is sensitive you can send it to [email protected]
