It calculates the delay of the next task from the `targetTimeMillis` of the currently finishing task when it should use `targetTimeMillis` of the next task.\n\n**Note**\nI did not test the behaviour of the @UiThread executor. It could be possible the issue occurs there as well.\n","author":{"url":"https://github.com/couchcrew-thomas","@type":"Person","name":"couchcrew-thomas"},"datePublished":"2016-02-26T14:35:02.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1706/androidannotations/issues/1706"}
