[jira] [Created] (MYFACES-3170) [perf] use initialCapacity for ArrayList

[perf] use initialCapacity for ArrayList
----------------------------------------

                 Key: MYFACES-3170
                 URL: https://issues.apache.org/jira/browse/MYFACES-3170
             Project: MyFaces Core
          Issue Type: Improvement
          Components: General
         Environment: myfaces trunk
            Reporter: Martin Kočí
            Assignee: Martin Kočí
            Priority: Minor



new ArrayList() creates Object [10]  and in some situation it is not necessary. For example, UIInput.addValidator allocates ArrayList of size ten but in real usage nobody adds 10 validators to one component.

Analyze usage of new ArrayList() and myfaces code and use initialCapacity if possible.
