FATAL ERROR in native method: processing of -javaagent failed

But with the old version testng-eclipse plugins I run those tests
without any problems, maybe the version number earlier than 5.14.2.7.
I can't get those old version since I all updated to the latest
release.

Any idea about this problem?

[Roman Timushev]

I have exactly the same problem. As far as I understood, TestNG plugin
adds the latest testng.jar to classpath which is incompartible with
current version of JMockit.
I have not found a good solution yet.

[Roman Timushev]

More exact cause of this error is that JMockit tries to stub
org.testng.internal.MethodHelper.invokeMethod(Method thisMethod,
Object instance, Object[] parameters) method that doesn't exist in
latest testng.

[Cédric Beust ♔]

So it's not really an Eclipse plug-in problem and it's actually not a TestNG problem either since JMockit was using an internal method (which was refactored recently, like all good internal methods always end up being :-)).

I'll contact the JMockit people to see what we can do.

Cedric, did you contact the JMockit folks? How did it go?

[Cédric Beust ♔]

Hi Ronnie,

Yes, I'm in the middle of exchanging emails with Rogerio and we're trying to come up with better ways to integrate TestNG and JMockit. I have nothing concrete to report right now.
