Thanks for checking, I didn't realize all the changes in this area had 
been back-ported. I've looked at the bug report and it is a bit 
confusing. It was originally reported as being observed with 8u102 but 
the java -version output is a build from jdk7u-dev I think.

In any case, if ulimit -Hn is 64k then the highest file descriptor will 
be 65535. You may be right that they are change the limit dynamic, I 
can't otherwise explain the exception.
