ArrayIndexOutOfBoundsException when attempting to construct report

Gatling (Open-Source)

Hi,
Trying to generate a report from a concurrent run on several remote servers. Have already done so several times. Now, suddenly, I’m getting this:

GATLING_HOME is set to /home/ubuntu/gatling
Parsing log file(s)…
Exception in thread “main” java.lang.ArrayIndexOutOfBoundsException: -23146894

I have no idea why. Any suggestions? I’ve been able to generate reports just fine in the past.

I added my observations here https://groups.google.com/d/msg/gatling/u21be-M8A3M/elazxvgzCQAJ

Could you please provide a way to reproduce, eg a simulation.log?

4

I’d love to, but I’m afraid I don’t have those files any more. If I encounter the error again, I’ll post a followup.

Thanks

For me it happened with the attached file.

simulation.log (5.73 MB)

You sample works just fine for me (checked with both 2.2.4 and master).

Grasping at straws here but my report would be generated on a Debian machine, could this be of interest for you?

I don’t have a Debian, but I tested on OSX, Ubuntu and Fedora.
Anyway, I fail to see how such issue could be OS related.

I really suspect that don’t have 2.2.3 nor 2.2.4 deployed but actually run an older version.

My pom.xml references 2.2.4, I am using the maven plugin

<properties>
   <maven.compiler.source>1.8</maven.compiler.source>
   <maven.compiler.target>1.8</maven.compiler.target>
   <scala.version>2.11.8</scala.version>
   <encoding>UTF-8</encoding>

   <gatling.version>2.2.4</gatling.version>
   <gatling-plugin.version>2.2.4</gatling-plugin.version>

   <scala-maven-plugin.version>3.2.2</scala-maven-plugin.version>

I guess Debian is actually your CI platform.
Have you checked that it indeed took the pom/gatling upgrade into account and that it’s not actually running an old Gatling version?
