IndexOutOfBoundsException while using clustered query
-----------------------------------------------------

                 Key: ISPN-1588
                 URL: https://issues.jboss.org/browse/ISPN-1588
             Project: Infinispan
          Issue Type: Bug
          Components: Querying, RPC
    Affects Versions: 5.1.0.BETA5
            Reporter: Mathieu Lachance
            Assignee: Sanne Grinovero


when using clustered query with dist sync mode i'm running into index out of bound exception.

java.lang.IndexOutOfBoundsException: Index: 100, Size: 100
	at java.util.ArrayList.RangeCheck(ArrayList.java:547)
	at java.util.ArrayList.get(ArrayList.java:322)

i do not have any reproductible step, but here's what i know :
it only seems to happen under high contention ; when i'm running stress test.
when running a stress test i might get query that return over than 100 results.
tough i've also seen it happen on query that can only return few (4-6) results.
i never saw the stack trace with different index and size different than 100 (it's always the exact same exception).
i've also tried the lazy iterator to see if it would have a different behavior, but i get the same stack trace.

is there anything i could look up in the source code to debug and maybe find the repro steps ?

thanks,
