> As part of thee efforts to remove {{TypedJson}} and move from {{org.json}} to {{Jackson}} between {{1.8.0}} and {{1.9.0}}, the {{JSON}} string returned by the {{QueryDataFunction}} doesn't include the object type anymore within the array (at least for primitive types). The old version used to return results in the form {{\{"result":[["java.lang.String","v"],["java.lang.String","b"]]}\}}, while the new one uses {{\{"result":["v", "b"]\}}}.
> This function is used through {{DistributedSystemMXBean.queryData}}, so any user executing queries through {{JMX}} and relying on the [documented representation|https://geode.apache.org/releases/latest/javadoc/org/apache/geode/management/DistributedSystemMXBean.html#queryData-java.lang.String-java.lang.String-int-] to parse the results will fail as soon as they upgrade to {{1.9.0}}.
> Several parsing methods within {{DataBrowser.js}} *still use these deleted types* as well to create an internal representation that is later used to show the results in {{HTML}} so, starting with {{1.9.0}}, the query results are always shown as empty.
> {code:javascript}
> // This function creates complete result panel html
> function createHtmlForQueryResults(){
>   var memberResults = responseResult.result;
>   if(memberResults.length > 0){
>     if(memberResults[0].member != undefined || memberResults[0].member != null){
>       //console.log("member wise results found..");      
>       for(var i=0; i<memberResults.length; i++){
>         //console.log(memberResults[i].member);
>         $('#memberAccordion').append(createHtmlForMember(memberResults[i]));
>       }
>     }else{
>       //console.log("cluster level results found..");
>       var accordionContentHtml = "";
>       accordionContentHtml = createClusterAccordionContentHtml(memberResults);
>       var resultHtml = "<div class=\"accordion-content2\">"+ accordionContentHtml +"</div>";
>       $('#memberAccordion').append(resultHtml);
>     }
>   }else{
>     $('#memberAccordion').append("<span> No Results Found...</span>");
>   }
> }
> {code}
> We need to either re-factor the entire parsing logic to use the new format, or revert the changes to keep using the old format.
> Cheers.
