    Description

      Jar file format is based on zip file format.
      And jar tool seems to write out the code "0xFE 0xCA 00 00" in
      the extra field of the file format in generating a jar file.

      Is the extra field code " FE CA 00 00" a "MUST" thing in the view of jar file specification?
      In other words, is a JAR file required to have the magic number in the extra field?
