I'm planning to merge - would just like to get a measure of the impact on heap usage. Looking at ReentrantReadWriteLock I see that it contains three objects: a ReadLock, WriteLock, and a Sync (and pointers to the shared Sync in the r/w locks). The Sync itself looks quite complex, including a doubly-linked list of Nodes, which I think represent Threads that have acquired the lock. I gave up trying to calculate the heap usage by inspection since it seems to be allocating dynamically based on lock acquisition? So maybe some empirical measurement will help -- This is an automated message from the Apache Git Service.
