[Cucumber] Cucumber JUnit cannot generate the correct xml result format when adding option --step-notifications

[Tam Vo]

I cloned and ran cucumber-example from
https://github.com/cucumber/cucumber-jvm/tree/master/examples/java-gradle.
I configure javaexec in gradle task below:

task cucumber(dependsOn: testClasses) {
doLast {
javaexec {
main = "cucumber.api.cli.Main"
classpath = configurations.testRuntimeClasspath + sourceSets.main.output + sourceSets.test.output
args = ['--plugin', 'pretty', '--glue', 'gradle.cucumber', 'src/test/resources', '--junit,--step-notifications',
'--plugin', 'junit:output.xml'
]
}
}
}

I want to Scenario or When and When, Given, Then are the test step and test
case tag but in output.xml file, When is not a testcase tag now.
My Expected behavior:

<?xml version="1.0" encoding="UTF-8"?>
<testsuite name="Just a failing scenario" time="0.007" tests="3" errors="2" skipped="0" failures="0">
<testcase name="Just a failing scenario" classname="Just a failing scenario" time="0"/>
<testcase name="I run a failing step" classname="Just a failing scenario" time="0.007">
<error message="production failed here" type="java.lang.RuntimeException">java.lang.RuntimeException: production failed here

And actual behavior now:
