Description

NIOServerCnxnFactory static block has no used code:

/**

• this is to avoid the jvm bug:
• NullPointerException in Selector.open()
• http://bugs.sun.com/view_bug.do?bug_id=6427854
  */
  try { Selector.open().close(); }

  catch(IOException ie)

  { LOG.error("Selector failed to open", ie); }

But the jvm bug: JDK-6427854 : (se) NullPointerException in Selector.open()
has been fixed in JDK7 b08
