/**
 * Reads the classpath file entries of this project's .classpath file.
 * Returns a two-dimensional array, where the number of elements in the row is fixed to 2.
 * The first element is an array of raw classpath entries, which includes the output entry,
 * and the second element is an array of referenced entries that may have been stored 
 * by the client earlier. // ww  w .j a  v  a 2  s. co m
 * See {@link IJavaProject#getReferencedClasspathEntries()} for more details.
 * As a side effect, unknown elements are stored in the given map (if not null)
 * Throws exceptions if the file cannot be accessed or is malformed.
