> Given a test case [1], RI passes it while HY fails.
> The MockJSplitPane class extends javax.swing.JSplitPane and overwrite its setDividerLocation(int) method.
> The test case creates a java.beans.PropertyDescriptor object using "dividerLocation" propertyName, null read method, and "setDividerLocation" write method.
> Then, RI returns the correct method:
> "public void PropertyDescriptorTest$MockJSplitPane.setDividerLocation(int)"
> but HY returns a homony method but from its super class:
> "public void javax.swing.JSplitPane.setDividerLocation(double)"
> [1] Test Case:
> class MockJSplitPane extends javax.swing.JSplitPane {
> private static final long serialVersionUID = 3109235561744543400L;
> public void setDividerLocation(int dividerLocation) { super.setDividerLocation(dividerLocation); }
> }
> public void test_setWriteMethod_MockJSplitPane() throws Exception {
> Class<?> beanClass = MockJSplitPane.class;
> String propertyName = "dividerLocation";
> String setterName = "setDividerLocation";
> PropertyDescriptor pd = new PropertyDescriptor(propertyName, beanClass, null, setterName);
> assertEquals(propertyName, pd.getName());
> assertNull(pd.getReadMethod());
> Method expectedMethod = beanClass.getMethod(setterName, new Class[] { int.class });
> assertEquals(expectedMethod, pd.getWriteMethod());
> }
