Looks like problem with leak on file descriptors in EPollSelectorImpl constructor.

http://grepcode.com/file/repository.grepcode.com/java/root/jdk/openjdk/8u40-b25/sun/nio/ch/EPollSelectorImpl.java

We can catch problem if a pipe was created but EPollArrayWrapper initialization failed. 
This problems may happenes if descriptors count near limit.


EPollSelectorImpl(SelectorProvider sp) throws IOException {
  super(sp);
  long pipeFds = IOUtil.makePipe(false);
  fd0 = (int) (pipeFds >>> 32);
  fd1 = (int) pipeFds;
  pollWrapper = new EPollArrayWrapper();
  pollWrapper.initInterrupt(fd0, fd1);
  fdToKey = new HashMap<>();
}
