Karate Runner hangs at waiting for parallel features to complete

I am trying to execute some tests using Karate Runner -

@KarateOptions(tags = {"~@ignore"}) 
//@KarateOptions(features = "examples/test.feature")
public class KarateTestRunner {
    @BeforeClass
    public static void beforeClass() throws Exception {        
        //TestBase.beforeClass();
    } 

    @Test
    public void testParallel() {
        Results results = Runner.parallel(getClass(), 5);
        generateReport(results.getReportDir());
        assertTrue(results.getErrorMessages(), results.getFailCount() == 0);        
    }
}

When I try to execute my tests -mvn test -Dtest=KarateTestRunner -DfailIfNoTests=false It displays - { ","type":"log","logger":"com.intuit.karate.Runner","thread":"main","level":"INFO","categories":enter code here[],"msg":"waiting for parallel features to complete ..." } And it hangs here. No logs.

Can anyone please here.
