I'm seeing builds failing due to attempts to load ServletException on agent side when running mvn hpi:run on Kubernetes plugin. Not sure what differs compared to a regular run but in any case, this can be avoided. (similar to https://github.com/jenkinsci/git-plugin/pull/1652)
JUnitParser$ParseResultCallable.invoke creates a
hudson.tasks.junit.TestObject, which imports ServletException for a web method. This can actually be avoided because the exception is unused.
Also removed other usages of this exception which turn out to be unused.
Attached logs for reference
