----------------------------------

Hi,

I am not very pleased about your fix in BeanUtil:

public static String getUniquePrefix() {
        if (nsCount > 1000){
            nsCount = 1;
        }
        return "s" + nsCount++;
 }

Please correct me if I am wrong but why is nsCount static and not synchronized? Under heavy load strange side effects may appear.
Please tell me, why you do not use the counter per SOAP Thread- request-base and reset it before every new ADB serializiation? Each message could then start with '1' and would not interrupt with parallel messages.

> We are using current Axis2 release with ADB binding. Each Axis stub is reused after each call. After several calls, we have noticed, that some namespace-prefix counters are never reseted and will increase after every loop:
> <ns27:tag..> will result to: <ns1233:tag..> after several calls with the same stub instance. You can reproduce this behaviour if you just put a loop aroung a stub:
> while (true) {
> try {
>   stub.call(param);
> } catch (Exception e) {
>    e.printStackTrace();
> } finally {
>   stub.cleanup();
> }
> }
> It seems, that 'xmlWriter.getPrefix(namespace)' inside the ADB classes is not reseted after each call. 
> It would be better (performance and payload length), to reset counter (e.g. to ns1) back.
