> Use of default constructor of ResultsCollectionPdxDeserializerWrapper and
> getting an iterator from it results in NPE:
> {{SelectResults<Struct> sr1 = new ResultsCollectionPdxDeserializerWrapper();}}
> {{sr1.asList();}}
>
> Results in :
>
> {{java.lang.NullPointerException}}
> {{at
> org.apache.geode.cache.query.internal.ResultsCollectionPdxDeserializerWrapper.iterator(ResultsCollectionPdxDeserializerWrapper.java:52)}}
> {{at
> org.apache.geode.cache.query.internal.ResultsCollectionPdxDeserializerWrapper.toArray(ResultsCollectionPdxDeserializerWrapper.java:174)}}
> {{at java.util.ArrayList.<init>(ArrayList.java:178)}}
> {{at
> org.apache.geode.cache.query.internal.ResultsCollectionPdxDeserializerWrapper.asList(ResultsCollectionPdxDeserializerWrapper.java:208)}}
>
> Additionally, user reported exception with a code along these lines:
>
> {{When a query with `SUM` aggregate is called:}}
> {{select sum(totalHoldingsValue) from /ExternalAccounts where uniqueAcctId IN
> SET (‘4’,‘5’,‘6’,‘|')}}
> Per the ticket a code of this type:
> {{String query = “<trace>select sum(totalHoldingsValue) from
> /ExternalAccounts where uniqueAcctId IN SET (” + externalAccountNumbers +
> “)”;}}
> {{SelectResults<Struct> preResults = executeTotalsQuery(queryService, query,
> externalAccountsRegion);}}
> {{logger.info(“query = ” + query.toString());}}
> {{logger.info(“query return object= ” + preResults.getClass().getName());}}
> {{logger.info(“query return size= ” + preResults.size());}}{{Iterator it =
> preResults.iterator();}}
> {{if (it.hasNext())}}{{{ logger.info(“query return = ” + it.next()); }}}
> {{List<?> results = (List) preResults.asList();}}}}
> threw an exception :
> {{Index: 0, Size: 0}}
> {{java.util.ArrayList.rangeCheck(ArrayList.java:653)}}
