Apache jmeter - 2.10 - Null point exception while

The Jmeter script runs fine on apache-jmeter2.8. I upgraded recently to apache-jmeter-2.10 and I started getting Null Point exception.

I revert back to apache-jmeter2.8 and the script works fine.

The script is general login script and the failure happens when it is trying to post.

Let me know if you need more info.

回答1:

You may be facing this known bug that has been fixed in nightly build:

https://issues.apache.org/bugzilla/show_bug.cgi?id=55717

As a workaround, try changing http implementation to Java instead of HttpClient4 implementation.

If you want to give nightly build a try, see:

http://jmeter.apache.org/nightly.html

Read:

Installing JMeter runtime

Download the _bin and _lib files

Unpack the archives into the same directory structure

The other archives are not needed to run JMeter.

回答2:

The above error has been addressed in 2.11 version. Download and use the latest version of jmeter 2.11 and check out your script.

No need to go for Nightly Build.
