Java 6 or Java 7 ?

I’ve an issue with last 2.0.0-SNAPSHOT :

Someone has this issue ?

2 differents issues:

We failed to realize that uncommons-math was compiled with JDK7. We’ll investigate if there’s something in the code that justifies it, otherwise we’ll recompile it so that Java 6 bytecode is emitted.
Could you share your simulation.log somewhere so that we can reproduce, please?

Cyril_Souti · May 27, 2014, 10:33am

I’ve attached simulation.log with Java7.

simulation.log (761 Bytes)

Cyril_Souti · May 27, 2014, 10:38am

Ok, for java 7, actually it’s a dependency issue with my nexus.

Excilys · May 27, 2014, 10:41am

If it’s a snapshot dependency issue, the problem is actually on our side, but we haven’t been able to fix it yet: https://github.com/excilys/gatling/issues/1821

Alex_Bagehot · May 27, 2014, 10:59am

I saw this last night when running a specific test of only 2 seconds duration. but if the test completes early/quickly this could affect other users.
ie. should be reproducible with something similar to

scn.inject(constantUsersPerSec(1).during(2 seconds))

Caused by: java.lang.IllegalArgumentException: highestTrackableValue must be >= 2 * lowestTrackableValue

Excilys · May 27, 2014, 11:23am

JDK6 compatibility fixed: https://github.com/excilys/gatling/issues/1912

Note that we will drop it in Gatling 2.1.

Excilys · May 27, 2014, 11:30am

Histrogram bug fixed too: https://github.com/excilys/gatling/issues/1913

Thanks for reporting!

Shawn_Clark · May 29, 2014, 4:40pm

I have seen the “highestTrackableValue must be >= 2 * lowestTrackableValue” error a few times. It only occurs after the test run is done and normally when I only have used 1 user that has only one action during the simulation. It looks like an edge case error. As soon as I provide more users or have more actions per user then it isn’t there anymore.

Excilys · May 29, 2014, 5:09pm

If it’s the same stacktrace, it’s already been fixed. Please grab a fresh snapshot.

Cyril_Souti · June 24, 2014, 8:26am

Hi,
