> 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.
