mvn gatling:test throws java.lang.StackOverflowError error

I just upgraded my Gatling from 3.3 to version 3.7.6. Now when I try to execute mvn gatling:test or ./mvnw clean gatling:test -Dgatling.simulationClass==ai.slit.brb.gatling.simulations.ActSimulation, I get a StackOverflow Error.

I have tried most of the online solutions but none seems to work for me. What could I be missing?

I have tried to increase memory size, and all other suggestions but none seems to work for me.

Solution

  • Gatling's documentation recommends to check the demo projects. Please check the one for maven + Scala. You're missing the -Xss parameter.
