>> The jarsigner -verify command currently performs verification by reading from JarFile to navigate the central directory (CEN) headers. It is now enhanced to include cross-validation of entries between JarFile (CEN-based) and JarInputStream (stream-based) representations of the JAR. It emits earnings when detecting discrepancies between a JAR file’s central directory and its local file entries.
