RFR 8202292 : test/jdk/java/io/FileOutputStream/UnreferencedFOSClosesFd.java fails with "raw fd count wrong"

[Roger Riggs]

Hi Brian, Mandy,

Listing the open file descriptors can be a useful utility. Originally I 
thought it was a temporary and throw away code.
To be a utility it needed to be a bit more general (sending the output 
to a particular stream).
Thanks for the suggestions.

Please review:

Thanks, Roger
