The initial value of the ringBuffer is -1. So > ringBuffer.next() gives 0 for the first call. If we create a SyncFuture with > sequence = 0, even when we set it's done (ie. doneSequence = 0), it is still > not done since doneSequence == NOT_DONE == 0. Can we set NOT_DONE to -1, and > the initial doneSequence to -2? -- This message was sent by Atlassian JIRA (v6.2#6252)
