jmeter throwing "Empty TestPlan - see log file" while opening a test plan

Question

I am using jmeter 2.11 on macbook pro.

Jmeter throws an exception in the UI saying "Empty TestPlan - see log file", when I try to open a .jmx file which was created by my colleague. Its opening perfectly for him.

jmeter.log

Answer 1

I faced the same issue. My colleague created a test plan using Jmeter 2.12. I am having Jmeter 2.10. After upgrading to Jmeter 2.12 i overcame the issue, its working fine now.

Answer 2

What is java --version command output for you and your colleague?

As per JMeter 2.11: Top 5 Features and Updates guide JMeter 2.11 requires Java 6 to run as it's being built using this Java SDK version.

I would recommend switching to Java 6 SDK from Oracle and if your PC/OS is 64-bit take 64-bit version of Java SDK and see whether it resolves your issue.

There is a Bug 56080 which looks pretty like a cause for the error you're getting so switching to Java 6 may resolve it for you.
