@eolivelli @dlg99 added a unit test for commitSync, specifically on how acknowledgeCumulativeAsync is called inside doCommitOffsets. Let me know if there is any thing else required.

@dlg99, any idea when can this be merged if everything is good? Also, can a patch version be released with this fix ?
