Unfortunately yes, yesterday was the first time (that I can notice) in my
entire Java dev life :O
That's why, after reading the javadoc that I've attached, I've found that
it's a documented behaviour.
What I could add to the original doc is that it likely to happen on long
running applications and mostly OS dependent (not JDK!!!): that's why it is
difficult see it in common unit tests.
