> In case of large result  
> {code}
> private void processRequest(String act, HttpServletRequest req, HttpServletResponse res) {
> ...
> json = jsonMapper.writeValueAsString(cmdRes)
> ....
> {code}
> Will fail with OOME, beacuse jsonMapper.writeValueAsString(cmdRes) internally will create a StringBuilder and will try to allocate large amount of memory.
> This could be easily fixed by writing object directly to response output stream via. 
> {code}
> jsonMapper.writeValue(out, cmdRes);
> {code}
