/**
 * Checks for duplicate entries on the inpath compared to the Java build
 * path// w  ww.j  ava2 s. c o  m
 * 
 * This checks to make sure that duplicate entries are not being referred
 * to. For example, it is possible for the JUnit jar to be referred to
 * through a classpath variable as well as a classpath container. This
 * method checks for such duplicates
 * 
 * 1. if an inpath entry is on the build path, then remove it from checking
 * 2. resolve the remaining inpath entries 3. resolve the build path 4.
 * there should be no overlap
