Egidijus Vaisnora commented on WW-4237:
---------------------------------------

I propose something like this (instead of confition ((Object[]) 
requestedLocale).length == 1):
{code}
private Object findLocaleParameter(Map<String, Object> params, String 
parameterName) {
        Object requestedLocale = params.remove(parameterName);
        if (requestedLocale != null && requestedLocale.getClass().isArray()
                && ((Object[]) requestedLocale).length > 0) {
            requestedLocale = ((Object[]) requestedLocale)[0];

            if (LOG.isDebugEnabled()) {
                LOG.debug("requested_locale=#0", requestedLocale);
            }
        }
        return requestedLocale;
    }
{code}

>    Affects Versions: 2.3.15.1

>
> If there is passed several parameters "request_only_locale", then 
> I18nInterceptor creates and sets locale which is equals Array.toString.
> I18nInterceptor.findLocaleParameter checks for array but also checks that 
> array should be of the length == 1. If it is more than one, then no value is 
> fetched but whole array.
