TaskAdaptor extends QBeanSupport { protected void startService () throws Exception { getServer().getFactory().setConfiguration(task, getPersist()); NameRegistrar.register (getName (), task); if (task instanceof Runnable) { new Thread ((Runnable) task).start (); } } TaskAdaptor(); Object getObject();  }### Answer:
@Test public void testStartServiceThrowsNullPointerException() throws Throwable { TaskAdaptor taskAdaptor = new TaskAdaptor(); try { taskAdaptor.startService(); fail("Expected NullPointerException to be thrown"); } catch (NullPointerException ex) { if (isJavaVersionAtMost(JAVA_14)) { assertNull(ex.getMessage(), "ex.getMessage()"); } else { assertEquals("Cannot invoke \"org.jpos.q2.Q2.getFactory()\" because the return value of \"org.jpos.q2.iso.TaskAdaptor.getServer()\" is null", ex.getMessage(), "ex.getMessage()"); } assertTrue(taskAdaptor.isModified(), "taskAdaptor.isModified()"); } }
