title: ant support for java 9 addmods option
body: <p>I am trying to compile my java project with Java 9.
  I am using the java.xml.bind package so I need to use the -addmods option
  for compiling.  Ant 1.9.7 does not seem to support this new feature.
  Does ant support -addmods option for Java 9 compiler?  </p>
