 HBase's internal use of GSON is now done in a stand alone module named `hbase-shaded-gson` rather than as a part of the `hbase-shaded-miscellaneous` module. The relocated fully qualified class names are still the same.
 
 This internal artifact is also set to maintain JDK bytecode compatibility as appropriate for use with branches-1 based releases in addition to the existing use in later release lines.
