Initializing Jmockit with Intellij idea WARNING

Question

I am having issue running jmockit on idea. I have testng test case that uses jmockit to mock. I am getting:

WARNING: JMockit was initialized on demand, which may cause certain tests to fail;
please check the documentation for better ways to get it initialized.

Here is the order of jars:

Here in part 4 it is telling what is the order and i am making this order but still getting warning which later is causing problem.

Anyone knows what is the problem? I am using

• jdk1.6.0_25
• Intellij idea 11.1.2
• testng-6.3.1
• jmockit-0.999.16

You are using incomplete TestNG jar from Maven, you need to use the full distribution from the TestNG site ( testng.org/testng-xxx.zip ), see this answers for the details:
