StackOverflowError in Groovy scripts

    Details

    • Similar Issues:

      Description

      Due to a regression in Groovy 2.4 (GROOVY-7826) scripts using some of the core classes with complex generic type arguments (e.g. hudson.model.Run or hudson.model.Job) will cause a StackoverflowError.

      Run this script in Script Console to reproduce the problem:

      def foo(hudson.model.Run run) {}
      

      This affects Script Console, Pipeline, Job DSL, Groovy plugin (system Groovy script) and probably other plugins using the Groovy runtime provided by Jenkins core.
