Hi,
It's not random corruption, as it's the same across different machines.
We are getting timezone printing wrong, and this is I think a way of not printing the timezone.

It would be great to have more info/examples in the JBS issue.
The one example in the JBS issue contains "-eur" so perhaps part of a timezone name in Europe...

What timezone are the machines actually set to?
Is there a TZ variable set? like in JDK-8340465
