I've no idea if this is really a problem of the xunit plugin, but the problematic behavior is since the update of xunit from 3.0.5 to 3.0.6 (also reproduceable with 3.1.0)

I have two stages with checkout scm and a stage with a xunit call in between. After the second checkout the whole pipeline will marked as success even the pipeline is not finished.

I've attached a sample Jenkinsfile and the log files with different xunit versions.
