This bug leads to UserDefinedFileAttributeView/Basic.java failing on macOS 10.13 systems, the test is passing on 10.14 and 10.15. The change just means that FileStore.supportsFileAttributeView will return false when asked if it supports UserDefinedFileAttributeView.class.

Thumbs up!

Do you have any idea when fgetxattr() was fixed in 10.14? For example,
if it was fixed in 10.14.4, then it would be necessary to include a micro
version in the check. We may not care about that level of precision if
we presume that folks are running the version that we tested (10.14.6).
