Unable to serialize lists because of ConcurrentModificationException

XMLWordPrintable

    • workflow-cps-global-lib 2.18

      This keeps up reported as Flaked tests as it seems to clash with some other test (related activity) and gets retried correctly. (Using synchronized mocks makes no difference).

      Reproducible by https://github.com/jenkinsci/resource-disposer-plugin/commit/bc5f00008cc31a680e103dd7bd804bd64b0a4668 and mvn clean package. Not by mvn clean package -Dtest=AsyncResourceDisposerTest#combined of course.

          [JENKINS-41037] Unable to serialize lists because of ConcurrentModificationException

          Logan Highland added a comment -

          We ran into this issue on the first build of a branch pipeline job. Same exact stack trace as Bahram Parsapour ran into.

          Ryan Stewart added a comment -

          I am seeing the same issue when loading libraries dynamically using

          library()

          It doesn't seem to matter if the library statement is the first line in the pipeline, nor inside a node.

          I have noticed however that this will almost always happen on build #1 of a multibranch pipeline

          it does on occasion occur on other builds but less frequently 

          [Pipeline] Start of Pipeline
[Pipeline] library
Loading library libs@libs
[Pipeline] End of Pipeline

          Under discussion in https://github.com/x-stream/xstream/pull/222 but probably this will need to be split into distinct issues, one for each collection which is being concurrently modified during save, and each case fixed independently.

          workflow-cps-global-lib-plugin #100 should solve the most-reported issues. Looks like there are a couple more in other plugins.
