  warning: Ignoring InnerClasses attribute for an anonymous inner class
  (org.xbill.DNS.UDPClient$1) that doesn't come with an
  associated EnclosingMethod attribute. This class was probably produced by a
  compiler that did not target the modern .class file format. The recommended
  solution is to recompile the class from source, using an up-to-date compiler
  and without specifying any "-target" type options. The consequence of ignoring
  this warning is that reflective operations on this class will incorrectly
  indicate that it is *not* an inner class.
