[Joshua Cao]

> Not a clean backport, due to the following:
> * [warn(String s, Object... o)](https://github.com/openjdk/jdk11u-dev/blob/f700d37d2b3d8c23d50defc19853c68bb60027ab/src/java.xml.crypto/share/classes/com/sun/org/slf4j/internal/Logger.java#L80-L83) was not included in the original patch, and was added to tip in a later patch
> * Use HexDumpEncoder instead of HexPrinter, because HexPrinter does not exist in JDK11
> * Different copyright years
> 
> Changes pass the new jtreg test.
