BELUGA BEHR created HBASE-19682:
-----------------------------------
Summary: 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
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.
