RFR JDK-8143330: No appropriate CCC request for two new protected methods added in JDK9b93 by JDK-8141132

[Xueming Shen]

Hi

Please help review the change for 8143330.

Issue: https://bugs.openjdk.java.net/browse/JDK-8143330
webrev: http://cr.openjdk.java.net/~sherman/8143330/webrev

Cause: two implementation methods ABS.getBytes/initBytes were
mistakenly declared as "protected" and exposed to the public. Both
should be package private.

Thanks,
Sherman
