I've got an amd64 web app server running 6.0/tomcat 7.0/jdk 1.8.
Occasionally I get a lot of FDs building up, looking like this in
fstat:
$ fstat | grep internet.stream.tcp | head -1500 |tail -5
_tomcat java 88950 1585* internet stream tcp 0x0 *:0
_tomcat java 88950 1586* internet

Not so sure anymore whether this is a bug. The diff shows those
sockets also in netstat.
0x0 tcp 0 0 *.**.*CLO
