unexplaind periodic build fail on JUnit (AssertionFailedError)

[Eyal Edri]

Hi,

I'm seeing a periodic fail on Jenkins every few builds (10 in avg).
I've seen a bug (http://issues.hudson-ci.org/browse/HUDSON-8727) on Hudson
ver 1.395 on a similar issue and I upgraded to Jenkins 1.410 to solve it,
But I see it's still happening.

Is there still a bug in Jenkins or it's a problem in my project Junit
Tests?

The error msg:
