No problem, it's a good contribution for something that the maintainers 
in this area never got time to work on.

One issue is that has come up since the commit is that 
UserDefinedFileAttributeView/Basic.java is failing on macOS 10.13 
systems. I've created JDK-8259865 [1] to track it. I can't duplicate it 
on 10.14 and 10.15. I think the issue is that fgetxattr is not failing 
with -1/ERANGE when the buffer is too small. We may have to disable 
support for user defined file attributes on systems older than 10.14.
