Release Note

<!-- markdown -->
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.

Description

HBASE-23015 is buttoning up a needed move off of jackson 1 in branches-1. We've already got the implementation work in place to move onto the hbase-thirdparty relocated GSON, but we can't currently build because other dependencies included in the miscellaneous module is JDK8+ only and branch-1 needs to work for jdk7.

couple of options:

• make the entire hbase-thirdparty repo work with jdk7
• break out gson from the clearing house miscellaneous module and make just the new gson module jdk7 compatible
• make a jdk7 compatible miscellaneous module and move gson over there (in case we decide to move branch-1 off of other problematic libraries e.g. guava)
