Hello Matthias, I was talking to Daniel @dfuch yesterday and we were thinking of reducing the system property value (like you have it here). I thought he meant we would reduce it for all platforms and that way we wouldn't have to duplicate these test definitions for AIX.

It would be good to let Daniel have a look at this before integrating. You don't have to update the PR until you hear from Daniel.
