The driver is still doing that? Just curious. Yes, but to be threadsafe with a shared buffer you do need to synchronize as the driver does a series of operations to accumulate a string that need to be atomic. Synchronizing on each individual operation isn't enough. That said, it's pretty silly to write code that depends on a Statement being threadsafe :) -O
