*** 39,49 ****
   * Filter configured based on the input jdeps option
   * 1. -p and -regex to match target dependencies
   * 2. -filter:package to filter out same-package dependencies
   *    This filter is applied when jdeps parses the class files
   *    and filtered dependencies are not stored in the Analyzer.
!  * 3. -requires specifies to match target dependence from the given module
   *    This gets expanded into package lists to be filtered.
   * 4. -filter:archive to filter out same-archive dependencies
   *    This filter is applied later in the Analyzer as the
   *    containing archive of a target class may not be known until
   *    the entire archive
