> Use Collections.emptyList() For Empty List Values
> -------------------------------------------------

> Key: HBASE-19682
> URL: https://issues.apache.org/jira/browse/HBASE-19682
> Project: HBase
> Issue Type: Improvement
> Components: hbase
> Affects Versions: 3.0.0
> Reporter: BELUGA BEHR
> Priority: Minor
> Attachments: HBASE-19682.1.patch
>
>
> Use {{Collection.emptyList()}} for returning an empty list instead of
> {{return new ArrayList<> ()}}. The default constructor creates a buffer of
> size 10 for _ArrayList_ therefore, returning this static value saves on some
> memory and GC pressure and saves time not having to allocate a new internally
> buffer for each instantiation.
