Might be better to skip the test then by adding to the header:
*
* @requires os.family != "aix"
*
rather than the check in the test source
And maybe remove this:
```
if (System.getProperty("os.name").startsWith("Windows")) {
return;
}
```
And also state in header something similar for Windows.
a) consistency
b) a change is required to be pushed (and back-ported :please: either way
