Problem running my own protocol in 2.1.7

[Chris Phelps]

We have written our own Protocol/Action/ActionBuilder, and had this working against gatling 2.0.3. I've been trying to update this to newer versions of gatling, and am running into some trouble.

I spent a bunch of time trying to update to 2.2.2, but there seemed to be a lot of moved and renamed classes, without many examples, so I stopped for now at 2.1.7. I have my protocol pieces successfully building, and simulations building, but I fail upon simulation start with an error about Threeten TzdbZoneRulesProvider. I've included the trace below.  I also see an error about DataWriters not being initialized, but I assume for now these are caused by the former error.

Do you have any advice on how to proceed here? Is this a known issue, or do we have a strong inclination that this may be fixed by going to 2.2.2?

Thanks

Honestly, no idea what your issue are, as you went with custom developments.

What's sure is that we've stopped using threeten-bp (which was a backport of Java 8's JSR 310/datetime API for Java 6/7) in Gatling 2.2 as we went for Java 8 only support.

Thanks, Stéphane.

Turns out my problem was that I was building an assembly jar and including gatling-charts-highcharts. When I included that with provided scope things cleared up.

Thanks
