I am trying to implement Karate Labs framework within an already existing TestNG setup. But executing the test causes the thread to go WAITING stat indefinitely. Can someone identify the issue here

    @Test
    public void testRestCases() {
        try {
            String mName = "testRestCases";
            String path = staticPath + "apis.feature";
            LOG.info(CLASSNAME, mName, "Rest cases test started");
            Runner.path(path).parallel(1);
            LOG.info(CLASSNAME, mName, "Rest cases executed successfully");
        } catch (Exception e) {
            LOG.info(CLASSNAME, TLog.EXCEP_MSG, e);
        }
    }

I tried debugging the code to no avail. Here is the thread dump
