I was trying to run the example simulation using the latest Gatling bundle (gatling-charts-highcharts-bundle-3.9.0) on OS X Catalina and encountered a segfault in libnetty.
Some more detail:
gatling-charts-highcharts-bundle-3.9.0 $ bin/gatling.sh
GATLING_HOME is set to /opt/gatling/gatling-charts-highcharts-bundle-3.9.0
Do you want to run the simulation locally, on Gatling Enterprise, or just package it?
Type the number corresponding to your choice and press enter
 Run the Simulation locally
 Package and upload the Simulation to Gatling Enterprise Cloud, and run it there
 Package the Simulation for Gatling Enterprise
 Show help and exit
computerdatabase.ComputerDatabaseSimulation is the only simulation, executing it.
