Gradle creates TEST-junit.framework.TestSuite$1.xml when there is no test method - gradle

Question

I have an Test class that actually has no tests
public class TestNumbers3EmptyTest extends TestCase {
public void TestNumbers3EmptyTest () {
}
public void noddInJunit3(){
//nothing needed here
}
}
Gradle runs test but creates a file
build\test-results\test\TEST-junit.framework.TestSuite$1.xml
Content of the file
<?xml version="1.0" encoding="UTF-8"?>
<testsuite name="junit.framework.TestSuite$1" tests="1" skipped="0" failures="1" errors="0" timestamp="2020-12-17T08:17:55" hostname="INH-M123-W" time="0.004">
<properties/>
<testcase name="warning" classname="junit.framework.TestSuite$1" time="0.004">
<failure message="junit.framework.AssertionFailedError: No tests found in org.sample.numberutils.TestNumbers3EmptyTest" type="junit.framework.AssertionFailedError">junit.framework.AssertionFailedError: No tests found in org.sample.numberutils.TestNumbers3EmptyTest

HTML report from Gradle too uses the "incorrect" classname
Somehow the test name becomes "junit.framework.TestSuite$1". How can I make gradle write correct classname and use correct filename?
(We have a framework which runs the tests across many machines. The filename and testclassname are important information for the framework to do cleanup/retry etc)
