sun.misc.HexDumpEncoder is an internal private API that is used almost exclusively by the security library code. It should be moved out of sun.misc and into a package more appropriate to its use, sun.security.util.
HexDumpEncoder extends CharacterEncoder, which is slated for later removal, so the minimal implementation was copied in-place ( no new code ). http://cr.openjdk.java.net/~chegar/8144995/00/webrev/ -Chris. [1] https://bugs.openjdk.java.net/browse/JDK-8144995
