load test
--------------------------------------------------------------------------------------------------------

                 Key: HARMONY-6678
                 URL: https://issues.apache.org/jira/browse/HARMONY-6678
             Project: Harmony
          Issue Type: Bug
          Components: Classlib
    Affects Versions: 6.0M3
         Environment: All Operating Systems
            Reporter: Prashanth KS
             Fix For: 6.0M3
         Attachments: 001_HARMONY_6678.patch

An ArrayIndexOutofBoundsException is thrown when the toArray(T[]) method is invoked, under
load test with multiple threads. Concurrent updates to the collection results in changing
Iterator sizes. As per the Javadocs, the result of the toArray(T[]) should return as much
elements possible from the Collection. 

A toArray(T[]) method override has been implemented in ConcurrentSkipListSet and the bounds
check has been included in the base class AbstractCollection to prevent this exception.
