> * Thread 1 enters the synchronized block and executes up to `initialized = true`. It is suspended at this point > > * Thread 2 enters the method and sees `initialized = true` because this variable is volatile. However, `result` is not volatile so we have no guarantees that it will be updated until thread 1 leaves the synchronized block. > > * Thread 3 skips the initialization block and returns result, which is still null. @nfsantos This can't happen. Any thread which reads the updated value of `initialized = true` which only happens after updating `result`, it is bound to see all the changes of the thread updating `initialized` (which is thread 1 in this case) including the `result` variable. -- This is an automated message from the Apache Git Service.
