The thread run successfully and the jtl file is created as well.

I quite new on Jmeter and tried to see where that "size" attribute is currently locate to see how change it, but could not find it on any *.properties file

any though how can be this fixed, what the message is referring to?

thanks

Answer 1

This error is likely due to an incompatibility of JMeter with Java 17 (as mentioned by Dmitri T).

Whilst we wait for a fix, a workaround would be downgrading to Java 16. I can confirm this solved the issue for me.

Answer 2

I had the same issue with:

• MacOS big SUR version 11.6
• Jmeter 5.4.1 (installed via brew)
• Temurin 11 (LTS) OpenJDK & Temurin 8 (LTS) OpenJDK

Running Jmeter with Java 8 solved my issue. The problem was, that Jmeter always used Java 11. I struggled some days to find out, how to set the Jmeter Java version:

• set the correct Java 8 Home in: /usr/local/Cellar/jmeter/5.4.1/bin/jmeter:

  JAVA_HOME=$JAVA_8_HOME exec "/usr/local/Cellar/jmeter/5.4.1/libexec/bin/jmeter" "$@"

Maybe there are easier ways to set Java 8 for Jmeter - but this was the only solution which worked for me.
