ImmutableListCopy makes too many copies --------------------------------------- Key: ISPN-12351 URL: https://issues.redhat.com/browse/ISPN-12351 Project: Infinispan Issue Type: Bug Components: Core Affects Versions: 12.0.0.Dev03 Reporter: Dan Berindei Assignee: Dan Berindei Priority: Minor Fix For: 12.0.0.Final An array copy is not needed when creating a new {{ImmutableListCopy}} instance from another {{ImmutableListCopy}}. The constructor with 2 list parameters can also avoid one array allocation by pre-allocating the array, or by using one list's array when the other list is empty.
