> Improve ScriptUtils performance by doing early preallocation in String encode

> Key: RF-12652
> URL: https://issues.jboss.org/browse/RF-12652
> Project: RichFaces
> Issue Type: Enhancement
> Security Level: Public(Everyone can see)
> Components: core
> Affects Versions: 4.3.0.M2
> Reporter: Darius Ski
> Assignee: Darius Ski
> Priority: Minor
> Fix For: 4.3.0.M3
>
>
> In ScriptUtils.toScript(Object obj) method there is allocation of
> StringBuilder with default size (of 16 characters). When large sized strings
> are passed to this method ( for example in partial rendering user bean
> returns a String with custom JSON ), method incurs penalty due to
> reallocations ( both in GC pressure and CPU use).
> The preallocation size could be set to 1.6-2 of initial size, cause we know
> that String is getting escaped and inflated by both normal (*2) and unicode
> escapes ( \u00XX style * 6).
