Subject [jira] [Commented] (COLLECTIONS-700) Add a ConcurrentWeakHashMap
Date Wed, 31 Oct 2018 14:47:00 GMT


Gary Gregory commented on COLLECTIONS-700:

The whole idea is _avoid_ doing just that. Synchronizing the map locks the whole map on each
call, a concurrent version would be thread-safe but not lock the whole map. Also, synchronizing
the whole map still does not fix BEANUTILS-509, see that ticket.

A need for this was found to best support BeanUtils's BEANUTILS-509
> This issue is looking for a volunteer.
