-----------------------------------------
> SparkStarBarrierInterceptor injects (Byte) 0
> --------------------------------------------
>
> Key: TINKERPOP-2157
> URL: https://issues.apache.org/jira/browse/TINKERPOP-2157
> Project: TinkerPop
> Issue Type: Bug
> Components: process
> Affects Versions: 3.4.1
> Reporter: Daniel Kuppitz
> Assignee: stephen mallette
> Priority: Major
> Fix For: 3.4.3
>
>
> There are 3 tests that occasionally fail in
> {{SparkGraphComputerProcessIntegrateTest}}:
> * {{g_V_name_min}}
> * {{g_V_name_max}}
> * {{g_V_age_min}}
> In all cases, failure is a result of a mysterious {{(Byte) 0}}. Apparently,
> this zero gets injected by the {{SparkStarBarrierInterceptor}}. I came to
> this conclusion because I wasn't able to reproduce any of the failures after
> excluding this interceptor. However, the failures happen randomly*, so I
> can't say with 100% certainty that the interceptor is the problem.
>
> * on my system it never happened in the Docker builds, rarely in IntelliJ
> debug sessions, but quite often when I just run the test suite in IntelliJ
