An error occurred: null
jmeter
Solution
This happened to me as well. In my case, I was running Jmeter 2.13 on OpenJDK 1.8 on my 64-bit Linux machine. I fixed it by installing Oracle's Java instead, and switching to it with:
alternatives --config java
I'm a bit annoyed that I have to do this now, as it used to work before (I think).
Problem
When i am starting jmeter than it showing the follwing error An error occurred: null My process to start jmeter is root@L411:/opt/apache-jmeter-2.12/bin# sh jmeter An error occurred: null
