Claus Ibsen resolved CAMEL-8864.
--------------------------------
Resolution: Fixed
Thanks have added that property to the other codecs.
> Camel-Aggregator JDBC repository always overwrites old exchange

> Key: CAMEL-8864
> URL: https://issues.apache.org/jira/browse/CAMEL-8864
> Project: Camel
> Issue Type: Bug
> Components: camel-sql
> Affects Versions: 2.15.2
> Reporter: Pankaj Takawale
> Assignee: Claus Ibsen
> Priority: Minor
> Fix For: 2.16.0
>
>
> I'm using FlexibleAggregationStrategy to aggregate objects into collection. I
> found following issue where Aggregator ends up overwriting old collection
> with the new one.
> JdbcCamelCodec is not marshaling all of the exchange properties.
> E.g. it does not marshal exchange's 'CamelFlexAggrStrCollectionGuard'
> property.
> So next time Aggregator tries to fetch BLOB from database, oldExchange does
> not have above property.
> So following code creates new collection for each new object, and hence
> overwrites the old collection.
> private Collection<E>
> FlexibleAggregationStrategy::safeInsertIntoCollection(Exchange oldExchange,
> Collection<E> oldValue, E toInsert) {
> Collection<E> collection = null;
> try {
> if (oldValue == null ||
> oldExchange.getProperty(COLLECTION_AGGR_GUARD_PROPERTY, Boolean.class) ==
> null) {
> try {
> collection = collectionType.newInstance();
> //**EVERYTIME NEW COLLECTION as previous aggregation did not serialize
> COLLECTION_AGGR_GUARD_PROPERTY to database.
