Null Pointer exception during cbench run

Bug Resolved Done Michal Rehak Jan Medved Thu, 23 Jan 2014 13:16:05 +0000 Mon, 27 Sep 2021 09:01:02 +0000 Sat, 25 Jan 2014 17:30:12 +0000 General 0 1 <p>Hello,</p> <p>any null pointer exception signalizes that there are some data missing in the DTO's passed to the library.</p> <p>My guess is that the match is not filled. Needs further debugging.</p> <p>Regards<br/> Michal</p> <p>It only happens when flow programming is initiated from two-phase commit. It does not happen when an app fills all flow data and sends an RPC</p> <p>I have also tried to run Cbench with some logging.
