> ObjectUtils.identityToString(Object) and friends should allocate builders and
> buffers with a size.
> Calling ObjectUtils.identityToString(Object) will allocate a
> {{StringBuilder}} and append to it. The {{StringBuilder}} will reallocate
> it's internal {{char[]}} at least once since most strings end up being larger
> than the default 16 characters initially allocated by a StringBuilder (on
> Oracle Java 7).
> This change computes the strings parts first and then allocates a
> {{StringBuilder}} of the right size.
> Similarly, the {{identityToString}} methods that accept an existing
> builder/buffer can call {{ensureCapacity}} to avoid any extraneous
> allocations.
