> Project: Struts 2
> Issue Type: Improvement

> If you evaluate an OGNL expression which has null value, XWorkMapPropertyAccessor does the evaluation twice.
> First in line 81: result = super.getProperty(context, target, name);
> Second in line 91: return super.getProperty(context, target, name);
> Performance can be improved by removing the second evaluation.
> Line 91: return null;
> This saves an extra evaluation, and at this point we can be sure that the result can only be null.
> Patch is attached.
> Please review it.
