Summary

0003726: HashMapImpl bug

Description

(rep by Fiaz Hossein)

we recently hit a very nasty bug in our code that was cause by the following exception. We have been looking at this and the only logical explanation seems to be that the request object was accessed by multiple threads. We are still looking how that could have happened but do you know of bugs related to this area in HashMapImpl?
