Hi,
I am writing a custom plugin to publish cucumber test results to a quality
center database for internal reporting needs. To do so, I am using the
cucumber-jvm gherkin library to process the test result file as was done in
the cucumber-testresult-plugin. My code is working fine and processing the
results but when I also installed the cucumber-testresult-plugin on my
Jenkins instance and used that, I am seeing this error message when trying
to display the test results:
Status Code: 500Exception:
Stacktrace:
java.lang.ClassCastException: gherkin.formatter.model.Tag cannot be cast to
gherkin.formatter.model.Tag

I believe this can happen when there are classloader consistency issues.
I looked at the code for the cucumber-testresult-plugin and it is using the
XStream2[1] class to load the serialized test results from the disk (in the
load method above)[2] and then when it goes to process those results in the
tally method[3], it blows up. Is there a potential issue in the way the
XStream2 class is handling the classloading? I am running this on Jenkins 1.520
Thanks,
Peter
