>                 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
>
> 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
