IOException: "cannot find current thread"

XMLWordPrintable

    • workflow-cps 2.69

      Our server has intermittently been raising an exception which fails builds: 

      java.io.IOException: cannot find current thread

      Finished: FAILURE

      It happens across different projects, and we can't find any commonality between them that might explain how we're ending up in this state. The error is not repeatable – kicking off the build again usually results in a successful build.

      Jenkins ver. 2.164.1

      (Relevant?) plugin versions:
      Pipeline Multibranch: 2.20
      Pipeline: Groovy 2.63

      I found the line that is throwing the exception in the source code, which seems straightforward, but I don't know why that value is sometimes null.

      I'm happy to provide more information to help diagnose this problem if you need something more.
