Leonardo Uribe commented on MYFACES-3170:
-----------------------------------------
The improvement is minimal. It is not something really required.
> [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

> 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.
