If you get some idea on the conditions when this occurs then it would be 
useful.

To make sure there is nothing obvious, I ran JDK tests on Solaris 11.3 
system with the port Selector as the default. All the tests pass. I 
can't think of a scenario where port_dissociate could fail with EBADF. 
It is correct to ignore ENOENT as that occurs then the file descriptor 
registered with the port is closed by dup'ing.
