Appy commented on HBASE-19682: ------------------------------ Yeah, i was wondering that this might fail some tests because of immutable aspect of Collections.emptyList(). :-) > 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, HBASE-19682.2.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. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
