[PERF] Avoid unnecessary AbstractList$Itr instances - do not use java.util.Collections.emptyList() --------------------------------------------------------------------------------------------------
Key: MYFACES-3469 URL: https://issues.apache.org/jira/browse/MYFACES-3469 Project: MyFaces Core Issue Type: Improvement Reporter: Martin Kočí Priority: Trivial java.util.Collections.emptyList() is singleton instance of java.util.Collections.EmptyList class, but this class inherits from java.util.AbstractList and creates new garbage iterator java.util.AbstractList.Itr instance in every foreach loop. It is better to use own singleton instance (similar as google guava has) same for java.util.Collections.emptySet() -- This message is automatically generated by JIRA.
