Not sure if this is a plugin issue or a Jenkins issue, but unfortunately at some point the plugin stopped failing the build.

Jenkins version is 2.263.1

Plugin version is 1.8-18

As far as I can tell it generates mutations and ran pitest correctly. The returned kill ratio is 98.933% and we are aiming for 100.0% (Configured as a post build action)

I can see this in the logs "Kill ratio is 98.933% (4359 4406)" and viewing PIT Mutation Reports also shows the results (undetected) correctly

I've tried to remove the plugin from Jenkins and clean up the configs and reinstall the plugin but did not solve my issues.

Any suggestions I can try? Thank you!
