      Description

      When we try to access the current pipeline status by executing the following request:
      <pipline job name>/lastBuild/wfapi/

      We sometimes get the following exception when the pipeline is running:

      Note that it works most of the time. But at some point, during the pipeline build, we get always the error above. After some time everything is ok and we get valid json again.

            Found the cause - it's a complex set of conditions involved with how we find the start of in-progress parallel branches.

            I'm reworking the fix though because I spotted a second issue after installing patched SNAPSHOT version on my host (possibly not related).
