Description

I get stack overflow exception when i do aggregation with small completionSize only
I have about 50000 lines to process if i use .completionSize(1000) it's fine but if i do .completionSize(10) i got java.lang.StackOverflowError

from("direct:iSplitSomethingBefore")
                .routeId("myRouteId")

                .aggregate(header(FILE_NAME_ONLY), new GroupedBodyAggregationStrategy())
                .eagerCheckCompletion()
                .completionSize(10) // Only when i use small number
                .completionPredicate(exchangeProperty(SPLIT_COMPLETE))
                // Some code....
;

java.lang.StackOverflowError: null
